What is Linux? From smartphones to cars, supercomputers and home appliances, home desktops to enterprise servers, the Linux operating system is everywhere. Linux has been around since the mid-1990s and has since reached a user-base that spans the globe. Linux is actually everywhere: It?s in your phones, your thermostats, in your cars, refrigerators, Roku devices, and televisions. It also runs most of the Internet, all of the world’s top 500 supercomputers, and the world’s stock exchanges. But besides being the platform of choice to run desktops, servers, and embedded systems across the globe, Linux is one of the most reliable, secure and worry-free operating systems available. Here is all the information you need to get up to speed on the Linux platform. What is Linux? Just like Windows, iOS, and Mac OS, Linux is an operating system. In fact, one of the most popular platforms on the planet, Android, is powered by the Linux operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply, the operating system manages the communication between your software and your hardware. Without the operating system (OS), the software wouldn?t function. The Linux operating system comprises several different pieces: Bootloader – The software that manages the boot process of your computer. For most users, this will simply be a splash screen that pops up and eventually goes away to boot into the operating system. Kernel – This is the one piece of the whole that is actually called ?Linux?. The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the lowest level of the OS. Init system – This is a sub-system that bootstraps the user space and is charged with controlling daemons. One of the most widely used init systems is systemd? which also happens to be one of the most controversial. It is the init system that manages the boot process, once the initial booting is handed over from the bootloader (i.e., GRUB or GRand Unified Bootloader). Daemons – These are background services (printing, sound, scheduling, etc.) that either start up during boot or after you log into the desktop. Graphical server – This is the sub-system that displays the graphics on your monitor. It is commonly referred to as the X server or just X. Desktop environment – This is the piece that the users actually interact with. There are many desktop environments to choose from (GNOME, Cinnamon, Mate, Pantheon, Enlightenment, KDE, Xfce, etc.). Each desktop environment includes built-in applications (such as file managers, configuration tools, web browsers, and games). Applications – Desktop environments do not offer the full array of apps. Just like Windows and macOS, Linux offers thousands upon thousands of high-quality software titles that can be easily found and installed. Most modern Linux distributions (more on this below) include App Store-like tools that centralize and simplify application installation. For example, Ubuntu Linux has the Ubuntu Software Center (a rebrand of GNOME Software? Figure 1) which allows you to quickly search among the thousands of apps and install them from one centralized location. Why use Linux? This is the one question that most people ask. Why bother learning a completely different computing environment, when the operating system that ships with most desktops, laptops, and servers works just fine? To answer that question, I would pose another question. Does that operating system you?re currently using really work ?just fine?? Or, do you find yourself battling obstacles like viruses, malware, slow downs, crashes, costly repairs, and licensing fees? If you struggle with the above, Linux might be the perfect platform for you. Linux has evolved into one of the most reliable computer ecosystems on the planet. Combine that reliability with zero cost of entry and you have the perfect solution for a desktop platform. That’s right, zero cost of entry… as in free. You can install Linux on as many computers as you like without paying a cent for software or server licensing. Let’s take a look at the cost of a Linux server in comparison to Windows Server 2016. The price of the Windows Server 2016 Standard edition is $882.00 USD (purchased directly from Microsoft). That doesn’t include Client Access License (CALs) and licenses for other software you may need to run (such as a database, a web server, mail server, etc.). For example, a single user CAL, for Windows Server 2016, costs $38.00. If you need to add 10 users, for example, that’s $388.00 more dollars for server software licensing. With the Linux server, it?s all free and easy to install. In fact, installing a full-blown web server (that includes a database server), is just a few clicks or commands away (take a look at ?Easy LAMP Server Installation? to get an idea how simple it can be). If zero cost isn’t enough to win you over? what about having an operating system that will work, trouble free, for as long as you use it? I’ve used Linux for nearly 20 years (as both a desktop and server platform) and have not had any issues with ransomware, malware, or viruses. Linux is generally far less vulnerable to such attacks. As for server reboots, they’re only necessary if the kernel is updated. It is not out of the ordinary for a Linux server to go years without being rebooted. If you follow the regular recommended updates, stability and dependability are practically assured. Open source Linux is also distributed under an open source license. Open source follows these key tenants: The freedom to run the program, for any purpose. The freedom to study how the program works, and change it to make it do what you wish. The freedom to redistribute copies so you can help your neighbor. The freedom to distribute copies of your modified versions to others. These points are crucial to understanding the community that works together to create the Linux platform. Without a doubt, Linux is an operating system that is ?by the people, for the people?. These tenants are also a main factor in why many people choose Linux. It?s about freedom and freedom of use and freedom of choice. What is a “distribution?” Linux has a number of different versions to suit any type of user. From new users to hard-core users, you’ll find a “flavor” of Linux to match your needs. These versions are called distributions (or, in the short form, “distros”). Nearly every distribution of Linux can be downloaded for free, burned onto disk (or USB thumb drive), and installed (on as many machines as you like). Popular Linux distributions include: LINUX MINT MANJARO DEBIAN UBUNTU ANTERGOS SOLUS FEDORA ELEMENTARY OS OPENSUSE Each distribution has a different take on the desktop. Some opt for very modern user interfaces (such as GNOME and Elementary OS’s Pantheon), whereas others stick with a more traditional desktop environment (openSUSE uses KDE). You can check out the top 100 distributions on the Distrowatch. And don’t think the server has been left behind. For this arena, you can turn to: Red Hat Enterprise Linux Ubuntu Server Centos SUSE Enterprise Linux Some of the above server distributions are free (such as Ubuntu Server and CentOS) and some have an associated price (such as Red Hat Enterprise Linux and SUSE Enterprise Linux). Those with an associated price also include support. Which distribution is right for you? Which distribution you use will depend on the answer to three simple questions: How skilled of a computer user are you? Do you prefer a modern or a standard desktop interface? Server or desktop? If your computer skills are fairly basic, you’ll want to stick with a newbie-friendly distribution such as Linux Mint, Ubuntu (Figure 3), Elementary OS or Deepin. If your skill set extends into the above-average range, you could go with a distribution like Debian or Fedora. If, however, you’ve pretty much mastered the craft of computer and system administration, use a distribution like Gentoo. If you really want a challenge, you can build your very own Linux distribution, with the help of Linux From Scratch. If you’re looking for a server-only distribution, you will also want to decide if you need a desktop interface, or if you want to do this via command-line only. The Ubuntu Server does not install a GUI interface. This means two things your server won’t be bogged down loading graphics and you’ll need to have a solid understanding of the Linux command line. However, you can install a GUI package on top of the Ubuntu Server with a single command like sudo apt-get install ubuntu-desktop. System administrators will also want to view a distribution with regards to features. Do you want a server-specific distribution that will offer you, out of the box, everything you need for your server? If so, CentOS might be the best choice. Or, do you want to take a desktop distribution and add the pieces as you need them? If so, Debian or Ubuntu Linux might serve you well. Installing Linux For many people, the idea of installing an operating system might seem like a very daunting task. Believe it or not, Linux offers one of the easiest installations of all operating systems. In fact, most versions of Linux offer what is called a Live distribution ? which means you run the operating system from either a CD/DVD or USB flash drive without making any changes to your hard drive. You get the full functionality without having to commit to the installation. Once you’ve tried it out, and decided you wanted to use it, you simply double-click the “Install” icon and walk through the simple installation wizard. Typically, the installation wizards walk you through the process with the following steps (We’ll illustrate the installation of Ubuntu Linux): Preparation: Make sure your machine meets the requirements for installation. This also may ask you if you want to install third-party software (such as plugins for MP3 playback, video codecs, and more). Wireless setup (if necessary): If you are using a laptop (or machine with wireless), you’ll need to connect to the network, in order to download third-party software and updates. Hard drive allocation (Figure 4): This step allows you to select how you want the operating system to be installed. Are you going to install Linux alongside another operating system (called “dual booting”), use the entire hard drive, upgrade an existing Linux installation, or install over an existing version of Linux. Location: Select your location from the map. Keyboard layout: Select the keyboard for your system. User setup: Set up your username and password. Author Nerdcore Computers

What Computer Parts do you need to build a New Computer you ask? Does this mean you want to build your own PC? That is absolutely splendid! Building your own Computer from individual PC Components has so many benefits compared to just going out and buying a pre-built PC: Also: It’s a lot of fun! The anticipation of the individual parts being delivered to your house, the shiny boxes with all the different components in them, not to mention researching what parts you actually need, which you are doing right now! By building your own Computer you gain a lot of insight into the inner workings of Hardware Components and how everything fits together. You will be able to troubleshoot if any problems arise later on much easier, than when you have no clue what is actually going on inside your New PC’s Cases. Knowing the ins and outs of assembling a Computer and what Parts a Computer needs will also let you upgrade your Computer in the future. Another very important factor is optimization. Knowing how a New Computer works also enables you to optimize it as much as possible for your type of work. You can optimize by buying the best parts for your specific workloads, be it Gaming, 3D Rendering, Modeling, Graphic Design, Video Editing or so many other purposes you can use a Computer for. Building your own computer also is a lot cheaper than getting a pre-built PC. You can usually save around 30% in Cost when researching, buying the PC Components individually, and assembling them yourself. And the best of it all, building a Computer is so easy, it’s kind of interesting that not more people are doing it! Anyway, we now definitely know that we are on the right track in looking into building our own Computer, that’s probably why you came here in the first place. If you already have a grasp on what general type of Computer you need, what specific Parts do we need to build a PC? Let’s see: New Computer Parts List (PC Components) Here is the Computer Parts List with all the basic Hardware Parts that you will need for a functioning PC: New Computer Case New Computer Motherboard New CPU [Processor] New GPU [New Graphics Card] (if no integrated GPU) New RAM [New Memory] New Storage Device (SSD, NVME SSD, HDD) New Cooling (CPU, Chassis) New PSU [New Power Supply Unit] Display device, Monitor New Operating System [OS] Input Devices, Mouse, Keyboard Let’s take a closer look at them: Case The Computer case is nothing more than a fancy-looking box that holds all of the PC’s components. It can be opened and closed and usually has pre-defined areas with screws and holes where all the other Components are supposed to be placed and attached to. PC Cases come in different colors, sizes, with or without fans, some have LED lights some don’t, some have glass side panels, some others look absolutely crazy. Usually, you can think of a PC Case as a black (or white) Box with some buttons on top. This is where all of your components will fit into when you are done building your PC. You don’t actually need a case, you could also just lay all of your components on the floor or mount them on the wall, some people do, but being able to just pick up the entire Computer by picking up the Case comes in handy. Some Cases that are extremely popular and often recommended are the NZXT H500 – ATX Mid-Tower or the Phanteks Enthoo Pro. Motherboard Next up is a very important part, the Motherboard. The Motherboard is a Printed Circuit Board that every other Computer Hardware Component will be attached to. It is like a central hub that manages and connects all of your other Parts. Image-Source: tweakpc.de The Motherboard has connectors for cables like power cables and data cables, slots for cards like GPUs & sockets for CPUs. There are also lots of little building blocks like transistors, capacitors, jumpers, and lots of other tiny parts, that all go towards making your different hardware components work well together. Check out the best Motherboards for the popular AMD Ryzen CPUs and Intel CPUs Processor (CPU) Into the Motherboard’s Socket, the CPU is plugged in. Every CPU type has a specific Socket, that has a name such as 2066, LGA1200, AM4, TR4, and so on, and the Motherboard will need the exact same socket to be compatible with the CPU. This is usually the first step in picking new parts for your own pc build. Pick a CPU, check what socket it has, and then pick a compatible Motherboard. Continue on from there. Image-Source: AMD / Intel A CPU is the Central Processing Unit of a Computer, and without it, nothing really works. Almost everything you do on a computer will have to be calculated by the CPU in some way, so having a fast CPU (high clocks and high core count) will make your PC faster. CPU Cooler Anything that draws power also generates heat and the CPU generates lots of heat. This means it has to be cooled to be able to operate flawlessly. What do we need for cooling a CPU? A CPU-Cooler! Some CPUs like the AMD Ryzen Series (e.g. 3900X/5600X) already have CPU-Coolers included in the CPU Box, but lots of others, like the popular Intel i9 12900K do not. Make sure you have a CPU-Cooler that is compatible with your CPU and Socket. It’s the same as with the Motherboard and CPU Socket. The Cooler has to fit the CPU and Socket. Example: Are you planning on buying an AM4 CPU like the AMD Ryzen 5900X? You need an AM4 Socket Motherboard and an AM4 compatible CPU-Cooler too. Easy as that! Air Cooled Tower CPU Cooler, Image-Source: bequiet There are two popular CPU-Cooler types. One is the Air-Cooled Tower Cooler (that you can see in the image above) and the other is an AIO Closed Water loop CPU Cooler. AIO Closed Waterloop Coolers tend to do a better job at cooling overclocked CPUs and CPUs that run hot for long periods of time. AIOs, though, can be noisier (usually have more fans and the added pump noise) and need more room in your PC-Case, as they are attached to the side of the case, connected to the CPU with some Water Pipes. The air-cooled tower CPU cooler is great at cooling short performance bursts, is nice and quiet, and usually takes up less room in the case. It is simply placed on top of the CPU where it sits and goes about its cooling work. Because different CPUs have different sizes and are mounted onto various socket-types, be sure your Cooler is compatible with the type of CPU you’ll get. Many CPU Coolers come with different mounting brackets to increase compatibility Graphics Card (GPU) Next up is the Graphics Card. Its purpose is the processing of anything that has to do with visuals and outputs these visuals (Images, User Interface, GUI) onto the Monitor. There are two main types of GPUs, the integrated GPU (iGPU) and a discrete GPU. The integrated GPU is integrated into the CPU. This means, some CPUs already have a graphics chip built-in and you will not need an additional GPU to attach a monitor to. Although dedicated/discreet GPUs and iGPUs are meant for similar tasks their performance and size differ greatly When your CPU has an integrated Graphics chip (such as the Intel i9 10900K CPU) you can connect your monitor to the display Adapter on the Motherboard. The thing with integrated GPUs though is: Their performance is very limited. They are usually good enough for light tasks such as Word-Processing and some minor Games but as soon as you want to dive into graphics-heavy tasks such as 3D GPU Rendering, High-End Gaming, Video Editing, Graphic Design, and many others, you will have to get yourself a discrete GPU. Image-Source: Nvidia A discrete GPU is a GPU that is not part of the CPU. It comes on its own printed circuit board (like the one in the picture above), that is then plugged into a PCI Express Slot on your Motherboard. Some modern GPUs include Nvidia’s RTX generation such as the RTX 3060 Ti, RTX 3070, RTX 3080. The competitor AMD also has a solid line-up with the AMD Radeon RX 6800 or 6800XT. The two Manufacturers, Nvidia and AMD are fighting a fierce battle in getting a lead over the other, but at the moment it seems as though NVIDIA would be the Brand to pick over AMD if you are looking for the maximum performance you can get out of a GPU. Memory (RAM) Random Access Memory (RAM) is the short-term memory part of the Computer if you would compare it to a brain. The RAM stores data that is actively being worked on by the CPU. RAM can read and write very fast but can’t retain information once the power is turned off. Image-Source: G.Skill RAM kits consist of RAM Modules such as the 4 colorful Modules you can see in the image above. You can get just one Module, 2 Modules, 4 Modules, or even 8 Modules as long as your Motherboard has sufficient RAM Slots. A Motherboard has RAM slots where RAM gets plugged in to. RAM comes in different capacities starting at around 4GB and going up to 64GB per Module on modern systems. Having more Modules, of course, will multiply your RAM capacity. Find out what RAM performs best for your future PC build and take a look at our guide to see how much you’ll need. Storage (HDD / SSD / NVME SSD) Because RAM can’t store anything without power and we do want to be able to turn off our computer from time to time, we need a storage medium that retains its stored data, even when the power is off. There are 3 main mass-storage types: The HDD the SSD and the NVMe SSD. All three do pretty much the same, they store data for you. The main difference between the three is speed. An HDD (which still has mechanically moving parts) is the slowest of the three and will usually read and save Data at about 100MByte/s. An SSD will already read and write at around 500MByte/s and an NVMe SSD currently reads and writes sequential Data with up to 7000MBytes/s. So, yes, if you can swing it, get an New NVMe SSD such as the Samsung 970 Evo Plus! Both HDDs and SSDs are plugged into a SATA plug onto the motherboard via a SATA Cable. They also need Power that they get through a Power Cable from the PSU (Power Supply Unit, I’ll talk about that later!) The NVMe SSD, though, is plugged into the motherboard directly. It is about as small as a stick of chewing gum and needs no extra cables. Your Motherboard, of course, has to support NVMe SSDs and have an M.2 slot available. But almost all modern Motherboards nowadays have at least one of these. Highly recommended! More Cooling We talked about CPU Cooling a bit already. The CPU is not the only PC Component that needs cooling in a Computer. The GPU of course also needs cooling, but every discrete GPU that you can buy already comes with an attached Cooler on top of it, so we don’t have to worry about extra cooling for the GPU. Now, as the PC Case is usually closed and the PC Components inside the Case need preferably cool(ish) Air to be able to be cooled, there should be a way to blow colder air from outside of the PC’s case into the Case. This is done by attaching Case Fans to the inside of the case. These then pull in cool air at the front of your PC and blow the hot air out the back of your PC. This way the inside of the PC-Case and all of your PC Components ideally stay nice and cool. So do you need to get extra Case Fans? Usually not, as most Cases are shipped with extra fans that will do just fine for this purpose. If you are thinking about building a really quiet/silent PC though you might want to get higher quality Case Fans than are shipped with a standard case. Power Supply Unit (PSU) We picked a bunch of nice PC Components already, but nothing much will happen without a power supply to supply the PC with power. There are so many PSU brands with different wattage or efficiencies out there, that it can be quite difficult to decide which one to buy. The important thing is to know how much wattage your current PC Build will need to run stable and possibly how much you will need in the future if you are planning on adding more components, like extra/stronger GPUs or Storage Drives. You should then of course (now) buy a stronger power supply, that will later also be able to handle the extra components. Image-Source: Corsair Some great Power Supplies that I can recommend without hesitation, are the CORSAIR RMX Series RM650x and the Seasonic FOCUS Plus 650 Gold PSUs. beQuiet is another high-quality PSU Brand, but there might be others you prefer. That’s about it for our Computer’s Case. Everything that goes into the Case we have already discussed. We can close our case now and see what else we need to finish our PC Build. Monitor You will, of course, need some kind of display device such as a monitor to be able to see what’s going on. Monitors come in all kinds of sizes, colors, resolutions, aspect ratios, and so on. A popular modern Display usually is a 24” or 27″ Full HD / 4K Monitor from Brands such as Asus, Dell, LG, BenQ, Samsung, and many others. If you are looking for a Gaming monitor you might not need the IPS-type Panels that have better color display and contrast. If you are into Graphic Design and professional Color grading or Video Editing you should invest more money into a good Monitor. The Monitor is attached to either the discrete GPU or the Motherboard, depending on what type of GPU you have. Operating System Windows 11 is the currently leading Operating System that will let you use your PC. Lots of online Stores offer Volume License Keys that usually don’t cost you more than 215$ per license. Image-Source: Microsoft Windows 11 Pro Setup Of course, you will need to install the Windows 11 Operating System onto your Computer. There are several ways to do this. You can use a Win11 DVD if you have one and your PC has a DVD Player. Nowadays though, as optical drives are becoming a thing of the past, the Operating System is usually either downloaded directly from the Internet (for you to create your own boot medium on DVD or thumb drive) or you can buy it on a USB Stick (Thumb-Drive) that you can install Win10 from.

When Alienware announced a new design for its Aurora gaming desktops earlier this month it was clear a refresh is coming. And with Intel's new 12th Gen Alder Lake CPUs, it seems the time is right for Alienware to take on the throne for the best gaming PCs. Alienware is pushing the new design on two new PCs: the Intel-based Alienware Aurora R13, as well as the Alienware Aurora Ryzen Edition R14 which uses existing AMD processors. While the AMD version may get the fancy name and a spot in the new chassis, it's the Intel version that gets all of the bells and whistles thanks to Alder Lake. Alienware Aurora R13 Alienware Aurora Ryzen Edition R14CPUUp to 12th Gen Intel Core i9-12900K / KFUp to AMD Ryzen 9 5950XGraphicsUp to Nvidia Geforce RTX 3090 (24GB GDDR6X) or AMD Radeon RX 6900 XT (16GB GDDR6)Up to Nvidia Geforce RTX 3090 (24GB GDDR6X) or AMD Radeon RX 6900 XT (16GB GDDR6)RAMUp to 128GB DDR5-3,600 or 64GB DDR5-4,400Up to 128GB DDR4-3600StorageUp to 2TB NVMe M.2 PCIe SSD + 2TB 7,200-RPM SATA HDDUp to 2TB NVMe M.2 PCIe SSD + 2TB 7,200-RPM SATA HDDPower SupplyUp to 750W PlatinumUp to 750W PlatinumCoolingAir cooler, liquid cooler or Alienware Cryo-Tech Special Edition CPU liquid coolerAir cooler or liquid cooler CaseLunar Light, Dark Side of the MoonDark Side of the Moon NetworkingUp to Killer AX1675 Wi-Fi 6Up to MediaTek MT7921 Wi-Fi 6Starting Price$1,479.99 $1,249.99 Both the R13 and R14 use the same graphics, ranging from an Nvidia GeForce GTX 1650 up to an RTX 3090 on the Nvidia side, and AMD choices from the Radeon RX 5300 up to the RX 6900 XT. They also both get up to 750W Platinum-rated power supplies. The two desktops also get the same storage options, going from a 256GB M.2 SSD up to a 2TB NVMe M.2 PCIe SSD paired with a 2TB SATA HDD. But there are also some differences. The Intel-based Aurora R13, for instance, comes in both the white (lunar light) and black (dark side of the moon) versions of Alienware's new, larger chassis, while Ryzen Edition R14 owners are limited to just the dark colorway. Some of the contrasts are based on technology. Intel's 12th Gen processors support DDR5 memory. While both desktops can use up to a whopping 128GB of RAM, only the R13 gets DDR5. (The R13 goes up to DDR5-4400 on most configurations, except 64GB consisting of four 16GB modules, which runs at DDR5-4000, and the 128GB made from four 32GB sticks, which is at DDR5-3,600.) I imagine the AMD model will see an upgrade when team red releases chips that use the newer memory. The motherboard on the R13 also gets USB 3.2 Gen 2x2. While the R14 Ryzen Edition has both air and liquid-cooling options for the CPU, the R13 with Alder Lake also gets a new "Alienware Cryo-Tech Special Edition" CPU cooler. "We embrace opportunities to tackle gaming challenges and co-engineer solutions with all of our partners and you’ll see us continue to make investments in cooling for the best possible gameplay," Alienware told Tom's Hardware in a statement regarding the distinction. "The Alienware Aurora R13 features a new top-end CPU liquid cooling option (branded Cryo-tech Edition) that was co-developed and co-engineered alongside Intel. With this being a major architecture update for Intel, our teams worked together with the mission to get the most out of every core while also keeping the system cool and quiet. The Cyro-tech Edition is not designed for AMD CPUs." RECOMMENDED VIDEOS FOR YOU. Both the R13 and R14 have Wi-Fi options, including Realtek's RTL 882CE Wi-Fi 5 (AC) chip. But when you move up to Wi-Fi 6, there are differences. The R14 gets its sole Wi-Fi 6 option from MediaTek, while the R13 can choose between the Intel AX210 and Killer AX1675 options. Intel acquired Killer owner Rivet Networks back in May of 2020. Additionally, Alienware has new motherboards for the systems. Both are "custom," with the R13 using the Z690 chipset, while the R14 opts for B550. Of both the AMD and Intel boards, Alienware claims to have put power connectors on the edges in order to "reduce cable clutter and promote airflow." The company told Tom's Hardware that these motherboards won't be upgradeable. Alienware's parent company, Dell, is also releasing a redesigned XPS Desktop with Intel's Alder Lake chips. It, too, has a redesigned chassis, which is larger for improved airflow. The new XPS will be available sometime later this fall starting at $919.99.

D-Link DAP-1720 Wi-Fi AC1750 Range Extender Do you need a Wi-Fi extender? With so many options for upgrading your home network, like getting a new router or a mesh router, or adding a Wi-Fi extender or powerline extender, how do you know which is the best option for you? If most of your house is adequately served by the Wi-Fi router you already own, you may not need to buy a new one. A Wi-Fi extender is the perfect solution if you've got one room or one section of the house where your internet always seems to cut out. Wi-Fi extenders are great for knocking out a specific dead spot, for giving you a little more signal with a little more range, enough to reach that far room or give your Wi-Fi a little oomph to make it to the next floor. However, if you have large portions of your home or property that don't get adequate Wi-Fi, you may need to step up to one of the best mesh Wi-Fi systems, which use multiple devices to create a larger shared network. If you have multiple rooms with spotty coverage, or a far end of the house that your router can't reach, or want to extend your coverage out to the backyard or garage, then a mesh kit is the better choice. How to choose the best Wi-Fi extender for you How Much Should a Wi-Fi Extender Cost? The cheapest Wi-Fi repeaters will often sell for less than $50, and our current budget pick sells for half that. Newer signal boosting devices have support for the latest wireless standards and offering technologies like beam-forming and Mu-MIMO for enhanced performance will often cost more, but even the best extenders can be had for less than $200. And watch out for cheap discount range extenders, like the one in our Super Boost Wireless-N Wi-Fi Repeater review. The attractively low price also brings extremely poor performance. Plug-In or Desktop? While most signal boosters use small plug-in designs that connect directly to a wall outlet, they aren't the only option. Some of the best Wi-Fi extenders use larger designs that sit on a desk or shelf, more like a traditional router. These larger devices don't have the same size and weight limitations of plug-in units, allowing for better antenna placement and better internal hardware. Plug-in models, on the other hand, will often be less expensive and more convenient to install. Match Wi-Fi Standards: While you may not pay much attention to which wireless standard your router uses, it will definitely have an impact on how helpful your extender is. If your wireless router uses the current 802.11ac standard, you’ll want to be sure your extender does, too. The older 802.11n standard is slower and often is limited to one band, which will create a bottleneck in your Wi-Fi coverage, slowing down all of your browsing and streaming. But that's a problem only if your router is offering better speeds. If you have an older wireless-N router, then a matching extender will do the job just fine. Placement Is Everything: Both wireless routers and Wi-Fi extenders use radio waves to share data back and forth with your internet connection. You need to find somewhere that's close enough to the router to grab a strong signal to rebroadcast, but far enough away to extend the network's range to where it's needed. Need more help? Check out our guide to Wi-Fi extender placement. Consider an Upgrade: If your wireless router isn't providing the speeds or coverage you want, it may be better to skip the Wi-Fi extender entirely and get a new router. Newer models offer better performance, and mesh routers will let you expand your wireless coverage across even the largest home. (One of our editors traded in his router-and-extender combination for a Netgear Orbi mesh system. See why he says "This mesh router is the best thing I bought during the pandemic.") How we test Wi-Fi extenders Every Wi-Fi extender we review is evaluated based on a combination of in-depth performance tests and hands-on usage in a real home. This mix of real-world use and controlled benchmark testing gives us a clear picture of how well each device performs. We use Ixia's Ix Chariot testing software to measure throughput at a variety of distances and environmental conditions. This includes testing with the extender placed at 50 feet and 75 feet from the router. The software simulates traffic in a busy wireless network while measuring data flow back and forth. The results are shown in megabits per second (Mbps) at a distance from the extender, with higher numbers indicating better performance. Measuring the throughput at various distances also lets us determine the effective range of the extender, giving you a better understanding of how well a device will do in covering the farthest corners of your home. We also use each product in a real customers home, which has signal-thwarting brick walls and the sort of sturdy construction that basic routers struggle to contend with. In that environment we use the network for everything from listening to music and streaming video to performing additional tests. All nerdcore customers are totally satisfied with all the wifi design extenders our network technicians install. Author Nerdcore Australia

You configure this feature with Windows Admin Center or PowerShell, and you can set compression on SMB shares, client mapped drives, clients, servers, or even on individual file copies using robocopy. SMB compression is most effective on networks with less bandwidth, such as a client's 1Gbps ethernet or Wi-Fi network. It supports your favorite SMB options like SMB signing, encryption, and multichannel. Windows 11 and Windows Server 2022 both have this new capability. This is a game changing feature in a world where files and are bigger than ever on networks that are fuller than ever. SMB Security We added a raft of new SMB security features in Windows Server 2022 for use with client-server scenarios as well as failover clustering and high speed RDMA networking. Security is ever evolving and besides the new options below, we have additional security features coming retroactively to Windows 11 and Windows Server 2022. Windows Admin Center and the SMB settings for encryption and signing AES-256 SMB encryption protects your data from being read off the network. Windows Server 2022 now supports AES-256-GCM and AES-256-CCM, in addition to the primary AES-128 encryption used today. This isn’t some implication that AES security is flawed – there are no practical attacks that would allow someone without a key to decrypt AES-128 and none reasonably forecast, despite what the quantum computing marketing folks would have you believe – it’s to ensure that we met mandates like FIPS 197, NSA Suite B Cryptography, and others required by top secret networks. In fact, we still use AES-128 by default for performance reasons and let you opt into 256 bits with group policy and management tools. Windows 11 and Windows Server 2022 have this new capability. Accelerated signing SMB signing prevents tampering with data on the network, as well as relay, interception, and spoofing attacks. With Windows Server 2022, we added AES-GMAC acceleration to signing, meaning improved AES-NI hardware offloading provided by CPUs. When two AES-128-GMAC machines are signing SMB and running at least Nehalem processors – i.e., newer than 12 years old – you’ll see the latency of signed SMB really drop and transfer speeds improve, especially on busy processors. For more info on signing, check out Configure SMB Signing with Confidence. Windows 11 and Windows Server 2022 have this new capability. SMB Direct and RDMA encryption SMB Direct and RDMA supply high bandwidth, low latency networking fabric for workloads like Storage Spaces Direct, Storage Replica, Hyper-V, Scale-out File Server, and MS SQL server. Windows Server 2022 SMB Direct now supports encryption. Previously, enabling SMB encryption disabled direct data placement; this was intentional, but seriously impacted performance. Now we encrypt data before placement, leading to far less performance degradation while adding AES-128 and AES-256 protected packet privacy. Windows 11 Enterprise, Education, and Pro Workstation, as well as Windows Server 2022, have this new capability. Failover Cluster East-West security control Windows Server failover clusters use intra-node communications instances for cluster shared volumes (CSV) and the storage bus layer (SBL). Windows Server 2022 now allows granular control of encrypting intra-node storage communications for those networks beyond the “default” instance of SMB Server. This means that when using clusters and RDMA networks, you can decide to encrypt or sign east-west communications within the cluster itself for higher security, but not necessarily for north-south communications like file copies or Hyper-V Live Migration – and the reverse as well. You can control this with PowerShell currently, there’s more info at Security Settings for Failover Clustering. Windows Server 2022 failover clusters have this new capability. Storage Migration Service The Storage Migration Service migrates servers, their storage, and their SMB config from old Windows and Linux to modern Windows Servers and clusters running on-prem or in Azure. You can now also migrate from NetApp FAS arrays running NetApp ONTAP 9 or later. The process is almost identical to migrating from an old Windows Server 2008 or 2012 machine, except that now you point to a NetApp FAS and pick from its running CIFS SVMs, and you can migrate the data into folders on one or more volumes as NetApp storage doesn’t have drive letters. Furthermore, SMS now integrates with Azure File Sync cloud tiering! AFS cloud tiering allows you to use less storage in your Windows File Server and tier your data into Azure for backups and added ransomware protection. Windows Admin Center and the Storage Migration Service enabling AFS sync on each volume Applications must be aware of AFS cloud tiering, though; when they copy a large data set and AFS says “hey, this volume is full – please wait for me to dehydrate these old files into Azure,” the app has to pause IO. SMS understands this and you can configure AFS cloud tiering on your destination so that the migration and AFS happen simultaneously. For more info on AFS cloud tiering, see Understand Azure File Sync cloud tiering. Windows Admin Center and the Storage Migration Service about to begin a transfer with AFS enabled For steps on SMS, see Use Storage Migration Service to migrate a server. Windows Server 2022 and Windows Server 2019 with an update both have this new capability. Storage and Networking While not specific to File Services, the Networking, Hyper-V, and local storage teams have been busy adding more performance options for SMB and file servers to gain on Windows Server 2022. You’ll be configuring the new standalone storage bus cache feature based on your drive configuration; the networking features are on by default and just work! TCP & UDP Networking Windows Server 2022 implements TCP HyStart++ to reduce packet loss during connection start up - especially helpful in high-speed networks - and RACK to reduce Retransmit Time Outs (RTO). These features are enabled in the transport stack by default and provide a smoother network data flow with better performance at high speeds. Windows 11 and Windows Server 2022 both have this new capability. Furthermore, UDP is becoming a more popular protocol carrying more networking traffic. In Windows Server 2022 we added the game changing UDP Segmentation Offload (USO). USO moves much of the work needed to send UDP packets from the CPU to the NIC's specialized hardware. We also added UDP Receive Side Coalescing (UDP RSC) which coalesces packets and reduces CPU usage for UDP processing. “But” you exclaim, “SMB uses TCP and RDMA, what does this matter?” Read on, noble IT Pro, to see why this is important. Windows 11 and Windows Server 2022 both have this new capability. vSwitch networking The odds that your file servers are virtualized are extremely high and Windows Server 2022 improves the Hyper-V vSwitch with updated Receive Segment Coalescing (RSC). This allows the hypervisor network to coalesce packets and process as one larger segment. This reduces CPU cycles and segments will remain coalesced across the entire data path until processed by the intended application. This means improved performance in both network traffic from an external host, received by a virtual NIC, as well as from a virtual NIC to another virtual NIC on the same host. Windows Server 2022 has this new capability. Storage bus cache Windows failover clusters with Storage Spaces Direct have supported a caching feature for many years and now the option is available for standalone servers using Storage Spaces as the storage bus cache. Storage bus cache can significantly improve read and write performance by tiering smaller fast flash drives above slower but higher capacity drives. A diagram of SSD and HDD drives arranged into mirror cache tiers and parity capacity tiers SBC can work both as a read cache and a read-write cache, depending on your hardware. It adds performance to a file server without breaking the bank. Windows Server 2022 has this new capability. SMB over QUIC (preview) Finally, we come to the next generation of hybrid file services: SMB over QUIC. SMB over QUIC (preview) provides secure and reliable connectivity to edge file servers over untrusted networks like the Internet, and brings an "SMB VPN" to telecommuters, mobile device users, and high security organizations. QUIC is an IETF-standardized protocol with many benefits over TCP, including: All applications using QUIC travel over UDP and, by default, the firewall-friendly port 443 TLS 1.3 ensures encryption of all packets and a certificate provides non-repudiation Parallel streams of reliable and unreliable application data Improved congestion control and loss recovery All SMB traffic, including authentication and authorization, occurs within the tunnel and is never exposed to the underlying network. SMB over QUIC supports Kerberos but even if you decide to use NTLMv2, no challenge or response is exposed to the network. Author Nercdore Australia

This is one of the most common problem people experience. If your device does not point a specific issue, verify that it is properly connected to your router via the Ethernet cable or to the Wi-Fi for a wireless machine. Check the User Manual that came with your printer and follow the specified instructions to fix your printer. If your device is still not responding, contact the company’s tech support or professional technicians at Printer Repairs Centre. 6. My printer is very slow, what can I do? Printing speed depends on the quality of your device and on its maintenance. However, there are some things you can do to increase its speed: avoid double-sided printing as it slows down the process due to the rotation of the pages. In addition, you can speed up the process by printing documents in draft mode if you do not need high-quality output. 7. How can I avoid my printer jamming all the time? Paper jams are very common and frustrating. They are due to the paper not being aligned properly. Square the paper before putting it in the tray and don’t overfill it. You can also check your User Manual for troubleshooting solutions. If your printer keeps jamming, contact the company’s tech support or Printer Repairs Centre. 8. The text quality of the impressions is low, can I improve it? Quality output depends widely on the model and brand of your printer. Inkjet printers are adequate for everyday printing, but you should consider laser printers for your business impressions. Make sure you are not printing on draft mode and ensure that your ink cartridges do not need immediate replacement. For inkjet printers, you can also wipe the nozzle and line up the print head via the maintenance menu. For laser printers, check the ink cartridge and shake it several times from side to side. If the toner has “settled”, this manoeuver can resolve the issue. Printer Repairs Melbourne Author Nercdore Computers

Today marks the official retail availability of Intel’s 12th Generation Core processors, starting with the overclockable versions this side of the New Year, and the rest in 2022. These new processors are the first widescale launch of a hybrid processor design for mainstream Windows-based desktops using the underlying x86 architecture: Intel has created two types of core, a performance core and an efficiency core, to work together and provide the best of performance and low power in a singular package. This hybrid design and new platform however has a number of rocks in the river to navigate: adapting Windows 10, Windows 11, and all sorts of software to work properly, but also introduction of DDR5 at a time when DDR5 is still not widely available. There are so many potential pitfalls for this product, and we’re testing the flagship Core i9-12900K in a few key areas to see how it tackles them. Let’s Talk Processors Since August, Intel has been talking about the design of its 12th Generation Core processor family, also known as Alder Lake. We’ve already detailed over 16000 words on the topic, covering the fundamentals of each new core, how Intel has worked with Microsoft to improve Windows performance with the new design, as features like DDR5, chipsets, and overclocking. We’ll briefly cover the highlights here, but these two articles are worth the read for those that want to know. Intel Architecture Day 2021: Alder Lake, Golden Cove, and Gracemont Detailed Intel 12th Gen Core Alder Lake for Desktops Computer Repairs: CPUs, Chipsets, Power, DDR5, OCh At the heart of Intel’s processors is a hybrid, or heterogeneous, core design. The desktop processor silicon will have eight performance cores (P-cores) and eight efficiency cores (E-cores), the latter in two groups of four. Each of the cores is designed differently to optimize for their targets, but supports the same software. The goal is that software that is not urgent runs on efficiency cores, but time-sensitive software runs on performance cores, and that has required a new management control between the processor and Windows has been developed to enable Alder Lake to work at its best. That control is fully enabled in Windows 11, and Windows 10 can get most of the way there but doesn’t have all the bells and whistles for finer details – Linux support is in development. The use of this hybrid design makes some traditional performance measurements difficult to compare. Intel states that individually the performance cores are +19% over 11th Generation, and the efficiency cores are around 10th Generation performance levels at much lower power. At peak performance Intel has showcased in slides that four E-cores will outperform two 6th Generation cores in both performance and power, with the E-core being optimized also for performance per physical unit of silicon. Alternatively, Intel can use all P-cores and all E-cores on a singular task, up to 241W for the Core i9 processor. On top of all this, Intel is bringing new technology into the mix with 12th Gen Core. These processors will have PCIe 5.0 support, but also DDR5-4800 and DDR4-3200 support on the memory. This means that Alder Lake motherboards, using the new LGA1700 socket and Z690 chipsets, will be either DDR4 or DDR5 compatible. No motherboard will have slots for both (they’re not interchangeable), but as we are quite early in the DDR5 lifecycle, getting a DDR4 motherboard might be the only way for users to get hold of an Alder Lake system using their current memory. We test both DDR4 and DDR5 later on in the review to see if there is a performance difference. A small word on power (see this article for more info) – rather than giving a simple ‘TDP’ value as in previous generations, which only specified the power at a base frequency, Intel is expanding to providing both a Base power and a Turbo power this time around. On top of that, Intel is also making these processors have ‘infinite Turbo time’, meaning that with the right cooling, users should expect these processors to run up to the Turbo power indefinitely during heavy workloads. Intel giving both numbers is a welcome change, although some users have criticized the decreasing turbo power for Core i7 and Core i5. As we reported last week, here are the processors shipping today: Processors that have a K are overclockable, and those with an F do not have integrated graphics. The graphics on each of the non-F chips are Xe-LP graphics, the same as the previous generation. At the top of the stack is the Core i9-12900K, with eight P-cores and eight E-cores, running at a maximum 241 W. Moving down to i7 gives eight P-cores and four E-cores at 190 W, and the Core i5 gives six P-cores and four E-cores at 150 W. We understand that future processors may have six P-core and zero E-core designs. The Core i9-12900K, the focus of this review today, is listed at a tray price of $589. Intel always lists tray pricing, which means ‘price if you buy 1000 units as an OEM’. The retail packaging is often another +5-10% or so, which means actual retail pricing will be nearer $650, plus tax. At that pricing it really sits between two competitive processors: the 16-core Ryzen 9 5950X ($749) and the 12-core Ryzen 9 5900X ($549). Let’s Talk Operating Systems Suffice to say, from the perspective of a hardware reviewer, this launch is a difficult one to cover. Normally with a new processor we would run A vs B, and that’s most of the data we need aside from some specific edge cases. For this launch, there are other factors to consider: P-core vs E-core DDR5 vs DDR4 Windows 11 vs Windows 10 Every new degree of freedom to test is arguably a doubling of testing, so in this case 23 means 8x more testing than a normal review. Fun times. But the point to drill down to here is the last one. Windows 11 is really new. So new in fact that performance issues on various platforms are still being fixed: recently a patch was put out to correct an issue with AMD L3 cache sizes, for example. Even when Intel presented data against AMD last week, it had to admit that they didn’t have the patch yet. Other reviewers have showcased a number of performance consistency issues with the OS when simply changing CPUs in the same system. The interplay of a new operating system that may improve performance, combined with a new heterogeneous core design, combined with new memory, and limited testing time (guess who’s CPUs were held in customs for a week), means that for the next few weeks, or months, we’re going to be seeing new performance numbers and comparisons crop up. From Intel’s perspective, Windows 11 brings the full use of its Thread Director technology online. Normally the easiest way to run software on a CPU is to assume all the cores are the same - the advent of hyperthreading, favoured core, and other similar features meant that add-ins were applied to the operating system to help it work as intended at the hardware level. Hybrid designs add much more complexity, and so Intel built a new technology called Thread Director to handle it. At the base level, TD understands the CPU in terms of performance per core but also efficiency per core, and it can tell P-core from E-core from favoured P-core from a hyperthread. It gathers all this information, and tells the operating system what it knows – which threads need performance, what threads it thinks needs efficiency, and what are the best candidates to move up or down that stack. The operating system is still king, and can choose to ignore what TD suggests, but Windows 11 can take all that data and make decisions depending on what the user is currently focused on, the priority level of those tasks, and additional software hooks from developers regarding priority and latency. The idea is that with Windows 11, it all works. With Windows 10, it almost all works. The main difference Intel told us is although Windows 10 can separate cores apart, and hyperthreads, it doesn’t really understand efficiency that well. So its decisions are made more in regards to performance requirements, rather than performance vs efficiency. At the end of the day, all this should mean to the user is that Windows 10 tries to minimizes the run-to-run variation, but Windows 11 does it better. Ultimate best-case performance shouldn’t change in any serious way: a single thread on a P-core, or across several P-cores for example, should perform the same. Let’s Talk Testing This review is going to focus on these specific comparisons: Core i9-12900K on DDR5 vs the Competition Core i9-12900K on DDR5 vs Core i9-12900K on DDR4 Power and Performance of the P-Core vs E-Core Core i9-12900K Windows 11 vs Windows 10 Normally when a new version of Windows is launched, I stay as far away from it as possible. On a personal level, I enjoy consistency and stability in my workflow, but also when it comes to reviewing hardware – being able to be confident in having a consistent platform is the only true way to draw meaningful conclusions over a sustained period. Nonetheless, when a new operating system is launched, there is always the call to bulk wholesale move testing to a new platform. Windows 11 is Windows 10 with a new dress and some details moved around and improved, so it should be easier than most, however I’m still going to wait until the bulk of those initial early adopter issues, especially those that might affect performance are solved, before performing a flat refresh of our testing ecosystem. Expect that to come in Q2 next year, where we will also be updating to NVMe testing, and soliciting updates for benchmarks and new tests to explore. For our testing, we’re leveraging the following platforms: All other chips for comparison were ran as tests listed in our benchmark database, Bench, on Windows 10. Highlights of this review The new P-core is faster than a Zen 3 core, and uses 55-65 W in ST The new E-core is faster than Skylake, and uses 11-15 W in ST Maximum all-core power recorded was 272 W, but usually below 241 W (even in AVX-512) Despite Intel saying otherwise, Alder Lake does have AVX-512 support (if you want it)! Overall Performance of i9-12900K is well above i9-11900K Performance against AMD overall is a mixed bag: win on ST, MT varies Performance per Watt of the P-cores still lags Zen3 There are some fundamental Windows 10 issues (that can be solved) Don’t trust thermal software just yet, it says 100C but it’s not Linux idle power is lower than Windows idle power DDR5 gains shine through in specific MT tests, otherwise neutral to DDR4 Author Nercdore Australia

12 Point File Server Maintenance Checklist Here is a File Server Maintenance Checklist A file Server is an amazing tool. They work 24/7, without issue, but like any machine they do require some maintenance an checkups. Some form of Simple maintenance and monitoring can often prevent a server failure from turning into a server disaster. Our engineers have all the great stories to tell I’ve had people call in a panic that there server has crashed. We begin to investigate to discover that their RAID failed last year, their backups stopped three months ago and their disk reached 100% capacity, corrupting their database. If you use our managed services, you don’t have to worry about these things. We monitor, review and maintain things 24/7, but if you are managing your own server, here are twelve items that should be part of your server maintenance checklist. 12 Server Maintenance Tips 1. Verify your backups are working. Before making any changes to your production system, be sure that your backups are working. You may even want to run some test recoveries if you are going to delete critical data. While focused on backups, you may want to make sure you have selected the right backup location. 2. Check disk usage. Don’t use your production system as an archival system. Delete old logs, emails, and software versions no longer used. Keeping your system free of old software limits security issues. A smaller data footprint means faster recovery. If your usage is exceeding 90% of disk capacity, either reduce usage or add more storage. If your partition reaches 100%, your server may stop responding, database tables can corrupt and data may be lost. 3. Monitor RAID Alarms. All production servers should use RAID. More importantly, you should be monitoring your RAID status. In our decade plus in business, we have worked on countless systems where the RAID failed. As a result, a single disk failure caused a complete system failure. At Nerdcore Australia , we either use providers that monitor our RAID for us or we have setup direct RAID monitoring. Roughly I estimate that RAID fails in about 1% of servers per year. One percent may seem small, but a complete server failure can turn a simple drive replacement into a multi-hour disaster recovery scenario. 4. Update Your OS. Updates for Linux systems are release frequently. Staying on top of these updates can be challenging. This is why we use automated patch management tools and have monitoring in place to alert us when a system is out of date. If you are updating your server manually (or not at all), you may miss important security updates. Hackers often scan for vulnerably systems within hours of a issue being disclosed. So rapid response is key. If you cannot automate your updates, then create a schedule to update your system. I recommend weekly at a minimum for current versions and perhaps monthly for older OS versions. I would also monitor release notices from your distribution so you are aware of any major security threats and can respond quickly. 5. Update your Control Panel. If you are using a hosting or server control panel, be sure to update it as well. Sometimes this means updating not only the control panel itself, but also software it controls. For example, with WHM/cPanel, you must manually update PHP versions to fix known issues. Simply updating the control panel does not also update the underlying Apache and PHP versions used by your OS. 6. Check application updates. Web applications account for more than 95% of all security breaches we investigate. Be sure to update your web applications, especially popular programs like WordPress. 7. Check remote management tools. If your server is co-located or with a dedicated server provider, you will want to check that your remote management tools work. Remote console, remote reboot and rescue mode are what I call the 3 essential tools for remote server management. You want to know that these will work when you need them. 8. Check for hardware errors. You may want to review the logs for any signs of hardware problems. Overheating notices, disk read errors, network failures could be early indicators of potential hardware failure. These are rare but worth a look, especially if the system has not been working within normal ranges. 9. Check server utilization. Review your server’s disk, CPU, RAM and network utilization. If you are nearing limits, you may need to plan on adding resources to your server or migrating to a new one. If you are not using a performance monitoring tool, you can install systat on most Linux servers. This will provide you some baseline performance data. 10. Review user accounts. If you have had staff changes, client cancellations or other user changes, you will want to remove these users from your system. Storing old sites and users is both a security and legal risk. Depending on your service contracts, you may not have the right to retain a client’s data after they have terminated services. 11. Change passwords. I recommend changing passwords every 6 to 12 months, especially if you have given out passwords to others for maintenance. 12. Check system security. I suggest a periodic review of your server’s security using a remote auditing tool such as Nessus. Regular security audits serve as a check on system configuration, OS updates and other potential security risks. I suggest this at least 4 times a year and preferably monthly. Also, you may want to revisit the 10 immutable laws of security administration. Being Proactive Prevents Failures As part of our management services, we monitor over a dozen server health metrics. By keeping track of things like swap usage, loads, mail queue depth and more, our team of sysadmin often spot issues before they become failures. Should failures occur, our team can focus on fixing the issue rather than worrying about maintenance items. This allows us to resolve most service outages in minutes. We don’t have to stop and apply six months of OS updates to see if a known bug is the issue. We highly recommend automating server management and maintenance. If you cannot automate, then create a schedule and stick to it. When we first started in this business over 10 years ago, we did a lot of things manually. That works well for a few severs, but once you have dozens of systems to manage, you can miss things. Tools like Nagios, New Relic, Pingdom, sysstat and many other open source and SaaS products can help you keep tabs on your servers.

Microsoft has decided that Windows 11 is an ideal launch pad for an update to Notepad. The venerable utility will now receive a new dark mode as well as some practical improvements. However, not everyone will receive the new Notepad right away. For one, Microsoft is rolling out the new Notepad via the Dev Channel of its Windows Insider program. More importantly, Microsoft hasn’t said anything about making the new Notepad available to Windows 10—it seems to be a hook designed to entice you into getting Windows 11. So what does the new Notepad offer? The most obvious changes will be aesthetic: the rounded corners that are characteristic of the Windows 11 Mica design aesthetic, as well as a new dark mode that won’t blow out your retinas if viewed late at night. But there are two more practical improvements, even if they might seem a bit overdue. First, Microsoft is adding a new “find and replace” experience that looks more in line with Windows apps like Mail: a big drop-down box will let you hunt down specific words and phrases in your document. Second, you’ll be able to quickly fix any mistakes you might make via a feature Microsoft calls a “multi-level undo,” where you can tap CTRL-Z multiple times to undo in reverse order any mistakes you might have made. Unfortunately, such basic features as autosave haven’t yet made it to Notepad, forcing you to manually save every so often. (The current version of Notepad places a small asterisk next to the filename to indicate that unsaved changes have been made.) Numerous Notepad alternatives have been available for years, however, including Notepad++ and Metapad, both of which are free and open source. Microsoft’s tweaks to Notepad are among a number of updates Microsoft is making to its Windows 11 apps, including Paint, Photos, and even the Clock.

Three different state-sponsored threat actors aligned with China, India, and Russia have been observed adopting a new method called RTF (aka Rich Text Format) template injection as part of their phishing campaigns to deliver malware to targeted systems. "RTF template injection is a novel technique that is ideal for malicious phishing attachments because it is simple and allows threat actors to retrieve malicious content from a remote URL using an RTF file, At the heart of the attack is an RTF file containing decoy content that can be manipulated to enable the retrieval of content, including malicious payloads, hosted at an external URL upon opening an RTF file. Specifically, it leverages the RTF template functionality to alter a document's formatting properties using a hex editor by specifying a URL resource instead of an accessible file resource destination from which a remote payload may be retrieved. Put differently, the idea is that attackers can send malicious Microsoft Word documents to targeted victims that appear entirely innocuous but are designed to load malicious code via the template feature remotely. Thus when an altered RTF file is opened via Microsoft Word, the application will proceed to download the resource from the specified URL prior to displaying the lure content of the file. It's therefore not surprising that the technique is being increasingly weaponized by threat actors to distribute malware. Proofpoint said it observed Template injection RTF files linked to the APT groups DoNot Team, Gamaredon, and a Chinese-related APT actor dubbed TA423 as early as February 2021, with the adversaries utilizing the files to target entities in Pakistan, Sri Lanka, Ukraine, and those operating in the deep water energy exploration sector in Malaysia via defense-themed and other country-specific lures. Windows systems for geopolitical gains. "The innovation by threat actors to bring this method to a new file type in RTFs represents an expanding surface area of threat for organizations worldwide," the researchers said. "While this method currently is used by a limited number of APT actors with a range of sophistication, the technique's effectiveness combined with its ease of use is likely to drive its adoption further across the threat landscape."

Troubleshooting your printer is the best way to fix some issues you may be experiencing. Apart from turning it off and on, here are 4 quick ways you can troubleshoot your printer for common problems. Bad Print Quality Paper plays a key part in the print process. Genuine printer paper sold by the manufacturer will tend to print better than generic printer paper. In saying that, it is also key to match the printer settings to what you’re printing. Troubleshoot your printer by checking the setting and choosing the appropriate print quality settings for your printed material. My Printer Won’t Scan Anymore Scanner software can corrupt easily. As a quick fix, it is good to reinstall the printing software package. This will allow any updates to be applied to your computer. If the issue persists, there may be a hardware issue that needs to be repaired or replaced. Paper Jams Paper jams are generally caused by foreign materials in the interior of the machine, but here are a few tricks you should follow to avoid paper jams. Try fanning the stack of paper to reduce any static and dust when loading the tray. Don’t load the paper to the brim of the tray, just because you can fit two reams of paper in the tray, doesn’t mean you have too. Paper can be heavy, and if you’re not printing those numbers frequently, you don’t need the additional weight in the tray. Prints Too Slowly Tailor your settings to each job. There is no point printing high image quality on a text-only page. Using a high-quality setting when not needed can increase the print time. Put simply, the lesser the standard for print quality, the faster it will print. Another way to quickly troubleshoot your printer is by running a clean cycle on the printer. If you are still experiencing errors/problems, it may be time for a service. Book online and save $77!

Today marks an exciting milestone in the history of Windows. As the day becomes October 11 in each time zone around the world, availability of Windows 11 begins through a free upgrade on eligible Windows 10 PCs and on new PCs pre-installed with Windows 11 that can be purchased beginning today. Windows is a driving force for innovation. It’s an enduring platform for each one of us to create. And its home for over a billion people to do their jobs, live their dreams and connect with the people they love. We’re pumped to be launching Windows 11; the entire user experience brings you closer to what you love, empowers you to produce and inspires you to create. Windows 11 provides a sense of calm and openness. It gives you a place that feels like home. It’s secure and everything is designed to be centered around you. To fully understand the magic of Windows 11 you must get it in your hands. The gorgeous graphics, sounds and animations of Windows 11 along with the innovative and beautiful hardware from our partners and Surface provides an experience like none other. Bringing you closer to what you love Windows 11 brings you closer to what you love and is designed with you at the center. From the new Start menu and Taskbar, to each sound, font and icon you see, the team thought through every pixel and detail to bring you a more modern, fresh and beautiful experience. With Start at the center you have quick access to the content and apps you care about and through the power of the cloud and Microsoft 365 (sold separately) you can see recent files you’ve been working on regardless of which device you were using, even if it was an Android or iOS device. To get you closer to the content and information you care about we’re introducing Widgets, a new personalized feed powered by AI and the web. Opening your personalized feed with a click or a swipe from the left is smooth and seamless as Widgets slides across your screen like a sheet of glass. Whether it’s glancing at your day through Outlook calendar and To-Do list integrations, catching up on the latest headlines or tomorrow’s weather forecast, or viewing your favorite OneDrive photo memories, Widgets bring everything you love to your fingertips. Chat from Microsoft Teams is a new experience that helps bring you closer to the people you care about. With a simple click you can use a personal account to chat, voice or video call with your friends, family and other contacts regardless of the device or platform they’re on – Windows, Mac, Android or iOS. Microsoft Teams isn’t just for people with smart devices; your friends and family can join the conversation via SMS text messaging. Plus, you can open the full Microsoft Teams experience directly from Chat to bring your plans to life with event scheduling, quick polls, file sharing and more. The new Microsoft Store on Windows brings you closer to your favorite apps and entertainment—all in one place. The Microsoft Store on Windows not only brings you more apps than ever before; we’re also making it easier to search and discover new content with curated stories and collections. New apps are available today in the Microsoft Store on Windows, such as Canva, Disney+, Zoom, the Epic Game Store and so much more. To learn more about what’s new in the Microsoft Store, Empowering your productivity and inspiring your creativity Windows 11 features powerful new experiences that empower your productivity and inspire your creativity. We’re all multitasking more than ever on our PCs, from multiple monitors and browser tabs to editing documents in Word or PowerPoint. With Windows 11, we’re making it easier to focus and stay in your flow with Snap Layouts and Groups, and Desktops. Snap Layouts and Groups offer a more powerful way to multitask and optimize your screen real estate in a way that is visually clean. With new three-column layouts for larger screens, it has never been easier to have all the content you need at your fingertips perfectly arranged. With Desktops you can create individual Desktops that display different sets of apps to help you stay organized and focused, like making separate spaces in your home, and you can even customize each Desktop with its own name and wallpaper. Accessibility was considered from the start in the development of Windows 11, with inclusive design reviews of new and redesigned features. We’re proud that Windows 11 is the most inclusively designed version of Windows, built with and for people with disabilities. Windows 11 offers familiar assistive technologies like Narrator, Magnifier, Closed Captions and Windows Speech Recognition to support people across the disability spectrum. To learn more about accessibility in Windows 11 We’ve improved the experiences for touch in Windows 11 when you’re using a tablet without a keyboard. You’ll see more space between the icons in the Taskbar, adding bigger touch targets and subtle visual cues to make resizing and moving windows easier, as well as adding gestures. We’ve also enabled haptics with Windows 11 to make using your pen even more immersive – allowing you to hear and feel the vibrations as you click through and edit or sketch. Surface Slim Pen 2 (sold separately) is a great example of haptics in action. With as much time as we’re all spending on our PCs, sometimes you might want to type on your PC with your voice. We’re excited to introduce new enhancements in voice typing on Windows 11. Now, with voice typing your PC recognizes what you say, even automatically punctuating sentences for you. For developers, Windows 11 offers new tools and resources With Windows 11, we endeavored to make Windows a more open platform. We thought about the development process and what tools and capabilities you need to create amazing apps. We built Windows 11 with developers in mind. You can create and build apps using the tools, frameworks and languages that you know and love. We’re also embracing all your apps and will work to make them feel at home on Windows. Windows 11 is built for gaming Windows 11 was made for gaming, with innovative new features that can take your PC gaming experience to the next level. If your PC has an HDR capable display, Auto HDR will automatically upgrade over 1000 DirectX 11 and DirectX 12 games to high dynamic range, rendering a much wider range of colors and brightness. We also believe that player choice is important, so Windows 11 includes the ability to turn Auto HDR on or off on a per-game basis. Windows 11 also includes support for Direct Storage, a feature we first introduced on Xbox Series X and Xbox Series S consoles. When paired with an NVMe solid state drive and DirectX 12 GPU, games that implement Direct Storage can benefit from reduced load times and render more detailed and expansive game worlds. Windows 11 also includes the Xbox app built right in. Through the Xbox app you can browse, download and play over 100 high-quality PC games with Game Pass for PC (membership sold separately). And this October kicks off the three biggest months in Xbox history with incredible game launches including Age of Empires IV on Oct. 28, Forza Horizon 5 on Nov. 9 and Halo Infinite on Dec. 8. All three of these games will be available to Xbox Game Pass Ultimate and Xbox Game Pass for PC members on day one. Xbox Game Pass Ultimate members can also play 100+ Xbox console games on their PC without having to wait for a download, thanks to the power of Xbox Cloud Gaming (Beta) with the Xbox app. Enabling the hybrid workforces and classrooms of tomorrow Windows 11 is the operating system for hybrid work and learning. Through the rapid acceleration of digital transformation that we’ve seen over the last 19 months, it is critical for today’s organizations to be resilient and flexible. With the shift to hybrid work, where work is constantly changing, we understand the importance of an operating system that is flexible, consistent, secure and works how you work. That’s why Windows 11 is built on the consistent, compatible and familiar Windows 10 foundation that is easy for IT to manage. Beginning today, organizations can begin moving to Windows 11 on powerful PCs and through the cloud with Windows 365 or Azure Virtual Desktop. To learn more about how Windows 11 can empower your hybrid workforce, Windows 11 is designed for chip-to-cloud protection As we continue on our journey, feedback from our customers and the industry is so important to helping us shape a Windows that our customers love. To that end, we conducted a survey of Security Decision Makers in the U.S. from a range of industries and found that 75% of security decision makers, VP and above, feel that the move to hybrid work leaves their organization more vulnerable to security threats. This last year has proven that security needs to be built in from the hardware up, the chip to the cloud. In fact, 80% of respondents feel that software alone is not enough protection from emerging threats. Windows 11 was designed with security in mind to meet the challenges we will face in this new work environment and beyond. A new era for the PC begins today We are grateful to our entire ecosystem of partners who have played important roles in helping us prepare to get Windows 11 into the hands of our customers around the world. From OEM and app partners, to silicon, to retail, to our Windows Insiders, a launch of this global scale could not be achieved without them. On behalf of the entire team, we are pumped to bring you Windows 11, the Windows that brings you closer to what you love. We look forward to seeing the dreams and ideas you bring to life with Windows 11. This is just the beginning.

Should I Upgrade my iMac Hard Drive to a Solid State Drive? Wait, how can this work. Apple doesn’t upgrade iMac hard drives. So, is this doable? Yes another leading question here. Apple is all about selling new machines. So, if you neglected the solid state hard drive option during your purchasing configuration, oh well says Apple, buy another one! Or if you didn’t think about adding enough storage space, Apple again will put its hands up in the air like the just don’t care. But, don’t give up. nerdcore iMac repairs can help you. Most notably, non-authorized Apple repair providers do this. Why can’t authorized Apple repair shops do this? Well, see the same reasoning above. Apple wants you to buy new stuff all the time and preferably every year. So, they will not be opening up your iMac to help you out. Non-Apple shops have the liberty to do as they please. This means they can actually help the customer! Alright, so I have a little angst towards Apple. You bet we do. They don’t upgrade anything and are product-centric first before service which is tricky for everyone. At third-party Apple repair shops in Australia, for instance well, the good ones that is, they’ll upgrade anything and everything. This includes hard drive upgrades, RAM upgrades, and other parts. There’s no reason these parts cannot and should not be upgraded. As for the question here, is your iMac hard drive upgradeable? And should you do it? Yes and yes. Until Apple start soldering the solid state drives to the iMac logic board, and I’m sure it’s only a matter of time, your SATA or solid state hard drive (SSD) can be upgraded. You should certainly upgrade your regular SATA drive to an SSD drive as it’s ridiculously faster from startup, shutdown, accessing files, Internet, and everything in between. If you have a small SSD storage size, you can upgrade this as well, but it’s not necessary if you have enough space already. That’s up to you.

Microsoft confirmed there are four types of problems that might have given you a "This PC can't run Windows 11" error message if you used its PC Health Check tool. If you are missing the hardware or firmware necessary for Windows 11, the instructions below won't help -- you'll need to buy a new device to run the OS. Keep in mind that these instructions are written as broadly as possible. That's because Windows machines vary so much that it's not feasible to cover all the possible ways to enable TPM and Secure Boot across every device. For the most part, though, the process is similar enough across machines that you should be able to use the instructions as a guide and, where your computer differs, still identify the equivalent menu or label in your own system. If your machine is still covered by a warranty, always speak with the manufacturer first before doing anything that could potentially void it. If your machine is owned and maintained by your company or school, it may have a unique security configuration that your IT staff will need to handle. It's also a good idea to get in contact with your local PC repair shop; having a qualified professional on standby is the best way to get back on track if you get turned around or encounter roadblocks. Always back up your important files before making any big changes to your computer. Always. Just do it. You'll thank us later. If this is your first time working in a BIOS menu, stick close to the instructions and don't veer too far from the beaten path. We're on a very simple mission here, and nothing I recommend below will do any damage to your machine or data, but changing firmware settings in your BIOS menu can have a wide-ranging impact. There are few guardrails here, and you can lose a lot of important data very fast. Some mistakes can be permanent and, in most cases, there won't be any polite pop-ups gently asking whether you're sure you want to make those mistakes. You should definitely look around, explore your options and familiarize yourself with what's under the hood, but avoid changing any settings or saving any of those changes unless you know specifically what's going to happen when you do. Allright here is the solution. Go to rufus.com down load a copy this software an install it on your computer. Download a copy windows 10 professional iso - Download it here Download a copy of windows 11 professional iso - Download it here Complete the two operating system downloads- an use rufus to extract the iso onto a usb hard drive - the hard drive must be 16 gb or higher. Go to the folder on the windows 10 directory (source) look for the file install.wim Now copy the install.wim file from the windows 11 - sources directory into the windows 10 sources directory. Thats it so simple you have a windows 11 installation media file usb to install on any hard ware device even if its a pentium 1 machine. Boot up from the usb windows 10 stick an you can install windows 11 without any problems. The last thing you can try is going into the source folder of the extracted iso file you downloaded. An finding a file called appraiserres.dll open this file with notepad an do a find search on the following string uefi an tpm and delete all those lines with these entries. So once again look for first the uefi strings an delete every single one. Then do another search on tpm an delete all the entries from within the appraiserres.dll file. Once you have completed this save the file and restart the computer booting up from the usb. You will be able to by pass the system requirements with out any issues. Author Nerdcore Computers

Windows usually installs drivers automatically when it detects new hardware. Still, if you recently upgraded to Windows 10, you may need to update your hardware drivers manually. Some Windows Store apps only support newer webcam models, so your older device could be incompatible. Most desktop programs, however, still support older cameras. Windows 10 offers a feature that disables the internal webcam. Keeping your webcam turned off when not in use is a great idea to protect your privacy. However, it can cause problems if you accidentally toggle this feature. How to Fix a Webcam Not Working Follow these steps, in the order presented, to troubleshoot your webcam and get it working again. Check your antivirus settings. Antivirus software can occasionally interfere with webcams. Investigate the software settings to see if your antivirus prevents your camera from launching. Plug the webcam into a different computer. If you're using an external camera, plug it into another device to make sure it works. If you have problems with it on several computers, the problem is with the webcam. Check the device connection. Jiggling the cable or unplugging and plugging it back in can sometimes fix the problem. Check the USB port. Connection problems can occur on the computer's end. Plug something else into the USB port to rule out a faulty or mis-mapped port. Make sure the correct device is enabled. If you have a built-in camera and an external webcam plugged in, applications can get confused about which one to use. Check the application's settings and find the option to select your preferred device. Consult the manufacturer. For external webcams, check the user manual or the manufacturer's website for further guidance. Many manufacturers offer troubleshooting applications that check common device-specific settings. Update the webcam drivers (Windows 11, Windows 10, Windows 8, or Windows 7). If the webcam driver is out of date, it may not work properly. Change your webcam system settings (Windows 10, Windows 8). There may be a system setting that interferes with the function of the webcam.

Search engine optimization Nerdcore Computers (SEO) can help you with the process of improving the quality and quantity of website traffic to your website or a web page from search engines. Nerdcore Computers SEO targets unpaid traffic (known as "natural" or "organic" results) rather than direct traffic or paid traffic. This Unpaid traffic may originate from different kinds of searches, including image search, video search, academic search, news search, and industry-specific vertical search engines. As an Internet marketing strategy company, Nerdcore Computers SEO considers how search engines work, the computer-programmed algorithms that dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. Nerdcore Computers SEO is performed because a website will receive more visitors from a search engine when websites rank higher on the search engine results page (SERP). These visitors can then potentially be converted into customers. Our methods have a 90% success rate an you will notice a 400% profit in your sales margins if you use our website design an SEO methods. Our prices are cheap not like your normal SEO company that charge you a hundreds of thousands of dollars. Nerdcore Understands that most Search engines use complex mathematical algorithms to interpret which websites a user seeks. In this diagram, where each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Nerdcore computers SEO works out how your website an services interact with these spiders an customs tailors a ultra smart responsive website to work on all the search engines easily bringing new traffic to your door. Its not something that you will have to wait on it happens instantly. All the Websites are getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, that i have used since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded. Nerdcore Computers Methods Getting indexed The leading search engines, such as Google, Bing and Yahoo!, Yandex AOL use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. The Yahoo! Directory and DMOZ, two major directories which closed in 2014 and 2021 respectively, both required manual submission and human editorial review. Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links in addition to their URL submission console. Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click; however, this practice was discontinued in 2009. Search engine crawlers may look at a number of different factors when crawling a site. Not every page is indexed by the search engines. The distance of pages from the root directory of a site may also be a factor in whether or not pages get crawled. Today, most people who are searching on Google using a mobile device. In November 2020, Google announced a major change to the way crawling websites and started to make their index mobile-first, which means the mobile version of a given website becomes the starting point for what Google includes in their index. In May 2019, Google updated the rendering engine of their crawler to be the latest version of Chromium (74 at the time of the announcement). Google indicated that they would regularly update the Chromium rendering engine to the latest version. In December 2019, Google began updating the User-Agent string of their crawler to reflect the latest Chrome version used by their rendering service. The delay was to allow webmasters time to update their code that responded to particular bot User-Agent strings. Google ran evaluations and felt confident the impact would be minor. Preventing crawling To avoid undesirable content in the search indexes, Nerdcore SEO Melbourne webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots (usually ). When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam. In 2020 Google sun set standards (and open-sourced their code) and now treats it as a hint not a directive. To adequately ensure that pages are not indexed a page-level robots meta tag should be included Increasing Website prominence Nerdcore Computers SEO uses a variety of methods which increases the prominence of a webpage within the search results. Cross linking between pages of the same website to provide more links to important pages may improve its visibility. Page design makes users trust a site and want to stay once they find it. When people bounce off a site, it counts against the site and affects their credibility. Writing content that includes frequently searched keyword phrase, so as to be relevant to a wide variety of search queries will tend to increase traffic. Updating content so as to keep search engines crawling back frequently can give additional weight to a site. Adding relevant keywords to a web page's metadata, including the title tag and meta description, will tend to improve the relevancy of a site's search listings, thus increasing traffic. URL canonicalization of web pages accessible via multiple URLs, using the canonical link element or via 301 redirects can help make sure links to different versions of the URL all count towards the page's link popularity score. These are known as incoming links, which point to the URL and can count towards the page link's popularity score, impacting the credibility of a website. Also, in the recent times Google is giving more priority to the below elements for SERP (Search Engine Ranking Position). HTTPS version (Secure Site) Page Speed Structured Data Mobile Compatibility AMP (Accelerated Mobile Pages) BERT White hat versus black hat techniques SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO. White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing. An SEO technique is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines are not written as a series of rules or commandments, this is an important distinction to note. White hat SEO is not just about following guidelines but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see. White hat advice is generally summed up as creating content for users, not for search engines, and then making that content easily accessible to the online "spider" algorithms, rather than attempting to trick the algorithm from its intended purpose. White hat SEO is in many ways similar to web development that promotes accessibility, although the two are not identical. Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses hidden text, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings. Search engines may penalize sites they discover using black or grey hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review. One example was the February 2009 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices. Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google's search engine results page.

In today’s digital world businesses are more focused on improving their website ability and agility to achieve business prospects, because millions of websites are used every day for a variety of purposes. Unfortunately, many of these websites aren’t user-friendly – while considering the first byte. Poorly optimized website performance is overwhelmed with a number of issues including slow loading times, being non-user friendly, user incompatibilities, and so on. These issues show that your website is not just losing conversion on the website, but in the future, this loss is magnified to worsen site results. The final impact – lots of potentials leads down the drain because of a few seconds difference. Loading time is the total time taken to present your website in front of visitors. So, a website taking more time to show up for users will tend to lose its visitors and conversions resulting in a high bounce rate. Therefore, Boosting the website performance from an SEO perspective enables you to achieve new benchmarks in the journey of customer acquisition. wondering how to improve? If you want to better your website performance and loading speed with improved user-friendliness for the users, you should look at what Google recommends. There may be plenty of reasons for your poor website performance, consider: heavy HTML, CSS, JAVA codes. Unoptimized images or videos or video links in your content. Redirects Improper cache handling Server hosting Increased blocking time More time to interact – FCP, FID, LCP Unused or hulking Plugins There are tools available to measure website issues, further grades are provided by the tools according to the performance, with the list of issues holding your web application from progressing. leverage these tools to refine optimization and have a better appearing website. Here are the fundamental ways for improving the performance of a website. By concentrating on a couple of different techniques, you can drastically improve the speed and overall performance of your site. 12 effective tips on how to increase the speed of your website and make your every effort pay off in the long run to beat your unhealthy performance. Tips to Improve Your Website performance: Upgrade Your Web Hosting Plan It’s fair to say most first-time website owners select a common hosting plan. These hosting plans are very easy, low-cost, and starter-friendly, and if your website remains the same, that hosting plan can be a perfect fit. But, if you give progressive content eventually your site will develop, and faces backing off. If that is your case, the best decision is to upgrade your web hosting plan. Then your users will be happy, your Search engine optimization (SEO) will remain strong, and your website will be able to grow and change as you need it to. Enable Leverage browser caching The main cause why browser caching is essential is because it cut down the load on your web server, which ultimately reduces the load time of the website for your users with increased page speed. When you visit a website page, your program downloads all content of the specific page just as normal static documents like CSS and JS files. Furthermore, when you visit another page of the same website, your browser starts downloading them once more. In any case, if you have enabled Leverage Browser Caching, it will just download the unique content of the web page and static files will serve from your program. In this way, you can accelerate the website speed optimization process. Enabling GZIP compression By enabling GNU Zip or GZIP your website could perform well in terms of loading time and speed, GZIP compresses your webpages from the server-side and will send that to your users’ browser. Where again these files are uncompressed and served from the browser as a result of your user query. It can help decrease the size of your website page, which can essentially diminish the time to download the asset, lessen information utilization for the user, and enhance the opportunity to initially render your pages. Clean up excess plugins Excess of plugins can make your activity harder and more confounded than it should be. This can back off your website’s stacking speed and furthermore, it can accidentally give security gaps where people can abuse it to get access to the backend of your website. If you have some plugins installed that you no longer use or find unessential, you should deactivate and uninstall them. Reduce HTTP Requests The more HTTP requests, the more extended time to load. What’s more, bigger files will take significantly longer to exchange. The most effortless approach to lessen the number of HTTP requests on your pages is to not utilize numerous pictures, contents, CSS, Flash, and so forth. Minify JavaScript and CSS Files Minification is the way toward limiting code and increase in your web pages and content files. It’s one of the primary strategies used to reduce load times and transmission capacity use on sites. Optimize Your Images The significance of images in connecting clients to your items has been proven. If your website takes over 3 seconds to load, clients are bound to desert it which will radically expand your bounce rate and in the long run, it will influence your conversions. Image optimization enhances Page load speed, SEO ranking, boost conversations, enhance user engagement. Change Your Website Theme The subject of your site can likewise influence page load speed. Regardless of how great your server configuration is, if your website theme has a complicated code, your site will stack lazily. Build it as per mobile-first design. Use a Content Delivery Network (CDN) The main purpose of using a CDN is to enhance your user’s experience and to supercharge your site’s performance. Yet, CDNs not just only ensure a faster experience for your website users, but also help to anticipate site crashes in case of traffic floods. Fix Broken Links The google rankings are based on hyperlinks. Connecting between the site’s pages is a fundamental feature. At the point when everything is well and great, each link on our site will lead precisely to the perfect spot. But sometimes Broken links on your site don’t give the best impression. To evade these potential entanglements, you should regularly check for broken links on your whole website. Use a Reliable CMS A website is the focal point of your entire internet marketing strategy and your CMS is the core of your website. A CMS removes the middle man and empowers you to refresh and alter the content of your site. You’ll pick up the capacity to make your site increasingly unique, more to-the-moment, and progressively profitable to your users. WordPress is the most reliable CMS that satisfies all your content management needs and WordPress developers like us can assure you that. Optimize Your Database Optimizing your MySQL database tables is one method for making enhancements to your website. This is something you ought to do all the time, particularly if you use WordPress or some different CMS that depends a lot on database utilization. Conclusion: Having a fast website has never been more imperative than it is today. Users want websites to be fast, if you fail to reach their expectations you will risk losing a lot of website traffic and, ultimately you lose your loyal users or your revenue. At Star Knowledge, there are three things we consider very seriously: website security, accessibility, and website load times/performance. We use some of the tools for performance testing which include GTmetrix, Pingdom, and Google’s Page Speed Insights. We pay more attention to the below things How long media assets take to load? This may indicate images in the content that are too large or too-high resolution. Are any scripts slowing down the site? Any CSS or JS files that can be compressed to make downloading and rendering quicker? Cookie-free domains HTTP 404 (Not Found) error.

We’re excited to share that OneNote on Windows will get a series of updates over the next 12 months. These updates include a visual refresh, the latest Microsoft pen and ink advancements, a new navigational UI layout option that can flex for customer preferences, and more! If you're wondering which OneNote app on Windows will receive the updates, here's the best part: no matter which OneNote app you use today, we have a path for you to get these updates. Today, OneNote supports two apps on Windows: the OneNote app installed with Office and the OneNote for Windows 10 app available in the Microsoft Store. Advances in Windows and Office will allow us to unify the two apps so that you'll have the simplicity of a single OneNote app on Windows while enjoying the interface and features you're already familiar with. Figure 2: Mock-up of updates coming to the OneNote app on Windows. What you'll start seeing: The OneNote app will get new features and key existing features currently unique to OneNote for Windows 10. OneNote for Windows 10 users will get an in-app invitation to update to the OneNote app. We anticipate invitations to start in the second half of 2022. We will have a future announcement dedicated to IT pros that will detail the available controls over the timing and experience of updating users to the OneNote app. What this announcement means for you and your organization: If you currently use the OneNote app, there is no action to take as you are on the fastest path to new features. If you currently use OneNote for Windows 10, there is no action to take today as the OneNote team is working to build features that will help you move over to the OneNote app more easily in the future. Until we have completed that work, you can continue to use OneNote for Windows 10. If you plan on newly deploying OneNote to your organization, we recommend deploying the OneNote app. We're excited about the future of OneNote and look forward to hearing your feedback to make OneNote the best place for your notes. Please continue to tell us what you think through the in-app feedback and in the comments below! For more information on the future of OneNote on Windows, see the FAQ below. Frequently Asked Questions about the OneNote app on Windows Q: Are you making a third OneNote app separate from the two existing ones? A: No, the current OneNote app is evolving to include new features and key existing features from OneNote for Windows 10. Once the team has done the necessary work for a smooth update, users on OneNote for Windows 10 will get the invitation to update to the OneNote app. Q: How do I tell which OneNote I'm using today? A: What's the difference between the OneNote versions? - Office Support (microsoft.com) Q: What's new for OneNote in Windows 11? A: Both OneNote apps will continue to run in Windows 11. Upgrading from Windows 10 to Windows 11 will not affect your OneNote apps. If you're starting Windows 11 from a clean installation or new device, OneNote for Windows 10 will not be installed by default, but will be available to download for free in the Microsoft Store app. Q: Do I need to buy Office to use the updated OneNote app? A: No, the OneNote app is also available as a free standalone version: https://onenote.com/download. Q: What if I'm using OneNote 2003, 2007, 2010, 2013, or 2016? A: The latest OneNote app is available as part of Microsoft 365 as well as a free standalone version from: https://onenote.com/download. Q: I'm an IT professional managing OneNote users.

Q: Will the updated OneNote app support my existing notebooks? A: Yes, all notebooks you use today in OneNote and OneNote for Windows 10 will continue to work in the updated app. Q: As a OneNote for Windows 10 user, when will I need to update to the OneNote app? A: After the in-app invitation is available, we recommend updating to the OneNote app by October 2025 when both Windows 10 and OneNote for Windows 10 will reach end-of-support. Q: If I'm using both apps today, should I uninstall OneNote for Windows 10? A: We recommend keeping OneNote for Windows 10 for now as we plan to provide extra checks for the integrity of your notebooks before moving to a single app. To keep OneNote for Windows 10 from launching when you click on notebook links, you can change default apps here: Change the default version of OneNote on your computer - OneNote (microsoft.com). Q: I'm currently using OneNote for Windows 10. Can I get the OneNote app before I receive the in-app invitation? A: We recommend waiting for the in-app invitation to ensure a smooth experience. For those who want the OneNote app earlier, the fastest way is by installing the OneNote app here: https://onenote.com/download. Q: Will you be adding all the features unique to OneNote for Windows 10 that are missing in the OneNote app? A: While we won't be incorporating the entire list of features from OneNote for Windows 10 into the OneNote app, we are working to ensure that all the most loved features will continue to be a part of OneNote. We will follow up with the full list of features in a future announcement. Q: Will you be removing any existing features in the OneNote app? A: No. All existing functionality in the OneNote app, such as local notebook support, will continue to be supported on future updated versions. Q: Am I impacted if I use OneNote for macOS, iOS, Android, or Web? A: The OneNote team will continue to invest in OneNote for macOS, iOS, Android, and Web. There's no impact from this announcement on OneNote for these platforms.

Security researchers have discovered coronavirus-themed malware created to destroy users' computers. With the coronavirus (COVID-19) pandemic raging all over the globe, some malware authors have developed malware that destroys infected systems, either by wiping files or rewriting a computer's master boot record (MBR). With help from the infosec community, ZDNet has identified at least five malware strains, some distributed in the wild, while others appear to have been created only as tests or jokes. The common theme among all four samples is that they use a coronavirus-theme and they're geared towards destruction, rather than financial gain. MBR-rewriting malware Of the four malware samples found by security researchers this past month, the most advanced were the two samples that rewrote MBR sectors. Some advanced technical knowledge was needed to create these strains as tinkering with a master boot record is no easy feat and could easily result in systems that didn't boot at all. The first of the MBR-rewriters was discovered by a security researcher that goes by the name of Malware Hunter Team, and detailed in a report from SonicWall this week. Using the name of COVID-19.exe, this malware infects a computer and has two infection stages. In the first phase, it just shows an annoying window that users can't close because the malware has also disabled the Windows Task Manager. While users attempt to deal with this window, the malware is silently rewriting the computer's master boot record behind their back. It then restarts the PC, and the new MBR kicks in, blocking users into a pre-boot screen. Users can eventually regain access to their computers, but they'll need special apps that can be used to recover and rebuild the MBR to a working state. But there was a second coronavirus-themed malware strain that re-wrote the MBR. This one is a far more convoluted malware operation. It posed as the "Corona Virus ransomware" but it was only a facade. The malware's primary function was to steal passwords from an infected host and then mimic ransomware to trick the user and mask its real purpose. However, it wasn't ransomware either. It only posed as one. Once the data-stealing operations ended, the malware entered into a phase where it rewrote the MBR, and blocked users into a pre-boot message, preventing access to their PCs. With users seeing ransom notes and then not being able to access their PCs, the last thing users would thing to do is to check if someone exfiltrated passwords from their apps. According to analysis from Bleeping Computer, the malware also contained code to wipe files on the user's systems, but this didn't appear to be active in the version they analyzed. Furthermore, this one was also spotted twice, with a second version discovered malware researcher Nick Veloutsos, two weeks later. This time, the malware kept the MBR-rewriting capabilities but replaced the data wiping feature with a functional screen-locker. Data wipers But security researchers have spotted more than coronavirus-themed MBR-rewriters. They also spotted two data wipers. Both were discovered by Malware Hunter Team. The first was spotted back in February. It used a Chinese file name, and most likely targeted Chinese users, although we don't have information if it was distributed in the wild or was just a test. The second was spotted yesterday, and this one was found uploaded on the Virus Total portal by someone located in Italy. Malware Hunter Team described both strains as "poor wipers" because of the inefficient, error-prone, and time-consuming methods they used to erase files on infected systems. However, they worked, which made them dangerous if ever spread in the wild. It might seem weird that some malware authors create destructive malware like this, but it's not the first time that this happened. For every financially-motivated malware strain that security researchers discover, there's also one that was created as a joke, just for the giggles. Something similar happened during the Wanna Cry ransomware outbreak in 2017, when days after the original Wanna Cry ransomware encrypted computers all over the world, there were countless of clones doing the same thing for no apparent reason.

Apple Business Model vs. Microsoft Business Model: An Overview More than any other American companies, Apple, Inc. (NASDAQ: AAPL) and Microsoft Corporation (NASDAQ: MSFT) dominate the intersection of technology and consumer access. Even though they compete across a huge range of sub-industries, such as computing software, hardware, operating systems, mobile devices, advertising, applications, and Web browsing, each firm takes a different approach from an organizational and philosophical perspective. As of May 2020, AAPL had a market cap of around $1.35 trillion. Apple used to be the largest company in the world, but MSFT edges Apple out with a market cap of $1.40 trillion, riding on the strength in the growth of its cloud computing business. Apple and Microsoft are two of the biggest companies in the world, alternating the title of the world's most valuable company. Both companies have boasted a market cap of over $1 trillion. Apple's business model is based on innovation and consumer-centric devices. They are able to keep their base due to easy-to-use designs and data migration to new product lines. Microsoft built its success on the licensing of software such as Windows and Office Suite. Their business model has shifted, and they are releasing their own devices to compete with Apple's. Both companies are run differently with a different end purpose. They are both extremely successful and have revolutionized their respective industries. The Apple Business Model It is difficult to recall a modern American business so thoroughly dominated by the ideas and personality of one individual as Apple was under the tutelage of Steve Jobs. Jobs' remarkable innovations propelled Apple to unprecedented heights until his passing from cancer in 2011. During Steve Jobs' second reign—he was fired in 1985, returning in 1997—Apple returned to relevancy and revolutionized multiple subindustries. It took over the Walkman industry from Sony and completely redefined mobile phones when the iPhone was released in 2007. Apple easily bests its competitors in terms of hardware sales and high-end gadgets. Thanks to the company's early 2000s reputation as a nonconformist response to Microsoft, millennials grew up using Macs in large numbers. This is buoyed by the company's brilliant insistence on integrating its products, making it easier to keep using new Apple products and thus more difficult to switch to a competitor's interface; this is sometimes referred to as the "Apple Ecosystem Lock." The weakness in the Apple's business model lies in the historic success of the company's golden invention: the iPhone. Nearly three-quarters of all Apple revenue comes from iPhone sales, and no new, comparable innovation has taken off since its former CEO died and was replaced by Tim Cook. However, Cook has done a good job of preserving Jobs' legacy and has propelled Apple stock to all-time highs. The Microsoft Business Model For years, Microsoft dominated the computer industry with its Windows software; Apple was an afterthought for more than a generation of operating products. Before Google Web browsing began to dominate the market, Microsoft gave away Internet Explorer for free, driving Netscape and other similar companies out of business. The Microsoft revenue model historically relied on just a few key strengths. The first, and most important, is the licensing fees charged for use of the Windows operating system and the Microsoft Office suite. After a few years of increasing irrelevance in the race against Google and Apple, Microsoft unveiled a new vision in April 2014, instantly shifting focus to make Windows software more compatible with competitor products, such as the iPad. Microsoft also has a few successful products, highlighted by the Microsoft Surface and Surface Pro, that battle Apple devices such as the iPad. Moving forward, however, Microsoft realized that paid software is a more difficult sell in an age of low-cost alternatives. Additionally, tablets and phones are replacing PCs. A newer Microsoft business model has been telegraphed by CEO Satya Nadella, one that emphasizes product integration, a "freemium" software package, and a concentration on its cloud computing business. For example, Microsoft wants customers to be more engaged and fixated on its products. In 2015, CMO Chris Capossela explained this concept with a simple example: "Rather than using Skype on Sunday night to phone home, you are using Skype for messaging 15, 20, 30 times every single day. That's engagement." Special Consideration: Google's Business Model Unsurprisingly, the heart and soul of the Google revenue stream is its search engine and Web advertisements. While Google is not the only company to give away free services and bundle them with other goods, few do it as well or as successfully. Google services do not cost the user anything. Instead, Google lures in users and collects their data, and then sells access to eager buyers across the planet. Every marketing firm in the world wants the kind of information and repeat usage Google enjoys. Moreover, the company keeps getting better and more sophisticated at targeting consumers and businesses, syncing preferences and playing economic matchmaker. This no-fee model is not just profitable, it is very disruptive to Apple and especially to Microsoft. While Apple and Microsoft keep competing to find better and more innovative products to charge consumers, Google is all too happy to find a way to monetize activities for which users are eager to stop paying. Google does not charge for Android, which is one of the chief reasons manufacturers are so drawn to it. The Google Web apps, which bear a striking resemblance to Microsoft Office programs, are also free. Since Google began offering a free operating system and computer software, sales for Microsoft Windows and Office have slowed.

You can create a safer computing environment for your children, and in this guide, we'll show you the steps to complete this task on Windows 10. You can create a safer computing environment for your children, and in this guide, we'll show you the steps to complete this task on Windows 10. On Windows 10, you can add multiple accounts to share a device with other family members. If you have children, they can also have a personal space, but in a more controlled environment to make sure they have the safest experience possible while using apps, playing games, and browsing the internet. This can be a huge help now that people are working from home and the kids are not at school. This is all possible to set up using a child account, which you can then manage in a number of ways through the family settings in your Microsoft account. Using these tools, you can review reports of your children's online activities or limit the time they can spend in front of Windows 10 devices. You can also restrict age and screen time for apps and games, and can make sure they don't end up visiting websites that aren't suitable for them. In this Windows 10 guide, we'll walk you through the steps to properly set up a child account and manage its parental control settings. How to create a child account on Windows 10 How to manage a child account on Windows 10 Fixing common problems How to create a child account on Windows 10 To create and properly set up a child account on Windows 10, use these steps: Open Settings. Click on Accounts. Click on Family & other users. Under the "Your family" section, click the Add a family member button. Select the Add a child option. Confirm the email address of the young person you want to add. Quick tip: If the new member doesn't have an account, click "The person I want to add doesn't have an email address" option and continue with the on-screen directions. Click the Next button. Click the Confirm button. Click the Close button. Once you complete the steps, a standard account with limited access will be created for the child, and the new member will be able to sign-in immediately. However, you won't be able to control the account until they click the Accept Invitation button from the email invitation sent during the account creation process. Signing in first time To complete the set up of a child account, use these steps: Sign out of your account. Click the new account (it'll initially show as an email address). Click the Sign in option. Confirm the account password. Click the Sign in button. Click the Set up button (recommended). Click the Next button. Create a new PIN. Click the OK button. Click the Only save files to this PC option. (Unless you want your kid's data to get backed up in OneDrive.) Choose the privacy settings for the new Windows 10 account by turning on or off the toggle switch for each option. Click the Accept button. After you complete the steps, the next time the user signs in, the account will appear as the user's name, and they can sign-in directly into the desktop. How to manage a child account on Windows 10 Once the member has accepted the invitation, you can manage the kid account using the Microsoft family settings online. Using the online dashboard, you can view activity reports and limit screen time for apps and games. You can enforce rating for contents, apps, and games, and add money to allow the young person to make small purchases in the Microsoft Store. To manage an account for a family member using Windows 10, use these steps: Open Settings. Click on Accounts. Click on Family & other people. Under "Your family," click the Manage family settings online option. Alternatively, you can sign-in to your Microsoft account in your web browser, and open the Family tab. While in the family dashboard, you can view activity reports and manage various aspects of the account, such as screen time for the entire device and for apps and games, block innapropiate websites, and much more. Viewing recent activities Under the account name of the kid, click the Activity tab, and then turn on the Activity reporting toggle switch to start collecting activities from their Windows 10 devices. Once the option is enabled, you can see the websites they've been visiting, the apps and games they've been downloading and playing, and the time they've been spendinsg on their devices. If you can't stay on top of the daily activities, you can also turn on the Email weekly reports to me toggle switch to get a full report delivered to your email account. After enabling reporting, you can always come back and use the View activity from drop-down menu to select the day of activities you want to review. Limiting devices screen time In the Screen time tab page, you can enforce limits on the hours and days of the week the child can use their Windows 10 device. Using the parental controls, you can set two types of schedules to limit screen time. Under the "Device limits" section, you can turn on the Use one screen time schedule toggle switch to use one schedule for all devices, including PC and game console. You can also turn on the screen time for each device (for example, Windows 10 or Xbox One) separately using the toggle switch on the right side. Once you decide how to set device limits, configuring screen time schedules is an easy process. Under the "Time limit" column, use the drop-down menu and select the number of hours that the family member is allowed to use in a given day. Using this option, you can also set the allowance to all day or block the day entirely. After specifying the hours that the child can use a device, click the hours timeline on the right, and define the time of the day that the new member is permitted to use time allowance. For instance, you can enforce two hours of computing time a day, which the kid can use between 4 p.m. and 8 p.m. On the same page, you can also add and remove multiple schedules as needed. After configuring the screen time, click the Save button to apply the changes. If you want to set the same time to multiple days, such as from Monday through Friday, click the Add time to multiple days option, select the time range and the days of the week, and click the Save button. Applying app and game limits Inside the App and game limits tab, similar to the device screen time settings, you can enforce screen time limits for apps and games to promote a healthier and safer lifestyle for young members. To start using this feature, turn on the App and game limits toggle switch. Then select the app or game you want to set screen limits, and turn on the toggle switch on the right side to enable restrictions. While in the app settings, click on the Weekdays or Weekends tab and use the slider to set the amount of time the member can use the app. Also, use the Allow from option to specify the time of the day that the member can use the time. For example, you can enforce to hours of Google Chrome time a day, which the child can use between 2 p.m. and 6 p.m. You can check out this guide with more details on using app and game limits on Windows 10, Xbox One, and Android. Applying content restrictions The Content restrictions tab includes settings that allow you to set an age limit to restrict inappropriate apps and games. Also, you can enable web filtering to block websites and search results that are known to be not suited for young people. In addition, you can restrict or specified the set of sites your child can access. Set age restriction To enforce age restrictions, simply turn on the Block inappropriate apps, games & media toggle switch. Once you enabled the option, use the Allow apps and games rated for drop-down menu to specify the age restriction (for example, 18-year-old). Set web filtering To start filtering online content not suited for young people, turn off the Block inappropriate websites toggle switch. Under the "Always allowed" section, you can add the websites that a child can visit manually. Simply specify the link in the box, and click the + button, and repeat the steps to add more sites. It's also possible to check the Only allow these websites option to explicitly set this list as the only websites a child can load in the web browser while blocking everything else. Similar to the process to allow websites, you can use the "Always blocked" section to add the links for the sites that you want to restrict. It's worth noting that if you want to use web filtering, inappropriate searches will be more effective using Microsoft Edge and Bing as the default search engine. If you want to restrict your child from using another search engine, which may not have safe search enabled, it's a good idea to add those sites to the blocked list, including Google.com, Yahoo.com, DuckDuckGo.com, and others. Also, because this feature only works with Microsoft Edge, enabling "Web browsing" will block other browsers, such as Chrome or Firefox, to help to keep your kids safer when surfing the internet. However, if you want to allow the use of another browser, you can unblock them from the Apps, games & media section, under "Always blocked." Adding money to account The Spending tab allows you to add money to your kid's Microsoft account to buy anything they want without breaking the bank. This feature works in combination with the Content restrictions settings to block the products they shouldn't buy, such as game rated for a much older audience. Ask to buy In the "Ask to buy" section, you can turn on the Needs organizer approval to buy things and Email me when they get stuff toggle switches to require authorization for apps, games, and entertainment they want to purchase in the Microsoft Store without the need to add funds. However, when you enable this option, it'll exclude things they buy with a gift card or money already in the Microsoft account. Adding funds To add funds to your kid's account, click the Add money button, specify the amount, and complete the transaction. (This process is not refundable. If you're not sure how it's going to work, start with a small amount, or use the "Ask to buy" option.) In addition to adding money, at the bottom of the family settings page, you can also view your child's purchase history. Fixing common problems Typically, after setting up a child account on Windows 10 and configuring the parental controls, settings will apply immediately. However, sometimes, you may come across some problems getting screen time and family activities working correctly. To avoid or get around common problems, make use of these tips: As soon as the child account has been created, you want to verify the account on Windows 10 on Settings > Accounts > Your info. Click the Verify link and follow the on-screen instructions to complete the process. If the settings aren't working, make sure the device is connected to the internet, and restart the computer to update the system settings. Sometimes, problems can also occur as a result of missing updates; as such,, make sure to check for new updates manually on Settings > Update & Security > Windows Update, and click the Check for updates button. We're focusing this guide on Windows 10, but using the Microsoft family settings, you can also manage other compatible devices, such as Xbox One and Android phones, including additional features like "Find your Child," and more.

Netgear has long been a name associated with quality internet, and indeed some of the best Netgear routers also make up the list of the overall best Wi-Fi routers. If you find yourself stuck at home working or trying to binge a TV show, but spotty internet is holding you back, one of these should improve your situation. Great for most homes: Netgear Nighthawk R6700 — AC1750 Editor's pick This AC1750 Wi-Fi 5 router has 2.4GHz and 5GHz radios to serve all your devices, and it has the performance to handle a standard household and family. Four LAN ports are available for your wired devices, and a USB-A 3.0 port can be used to connect external storage for easy sharing. Upgrade pick: Netgear Nighthawk RAX50 Wi-Fi 6 Staff pick The Netgear Nighthawk RAX50 is a solid option if you want to spend a little more on your router to get even faster speeds and Wi-Fi 6 capability. This router has four LAN ports, a 5GHz radio, two USB 3.0 connections, MU-MIMO technology, and six Wi-Fi streams for faster performance. Best budget: Netgear R6080 This Wi-Fi 5 router offers theoretical speeds up to 300Mbps and 700Mbps on 2.4GHz and 5GHz radios, ideal for smaller spaces and few users with light work. It includes four 100Mbps Ethernet ports on the back for wired devices, and two antennas will reach up to about 1,000 square feet. Best for gaming: Netgear Nighthawk XR500 gaming router This Wi-Fi 5 gaming router hits blistering AC2600 speeds across 2.4GHz and 5GHz radios, with tailored QoS to ensure your gaming PC or console receives the best speed. Four Gigabit LAN ports are included for wired devices, and four external antennas help boost range and reliability. Wi-Fi 6 gaming: Netgear Nighthawk Pro XR1000 This AX5400 Wi-Fi 6 router is an absolutely killer option for gaming thanks to a 1.5GHz CPU, six streams, beamforming, MU-MIMO, and four LAN ports. DumaOS 3.0 is included for total control over your network, and four external antennas help boost range. Best mesh network: Netgear Orbi RBK50 Upgrading to mesh is excellent for large homes with many users. The Orbi and its satellite can cover up to 5,000 square feet and offers combined tri-band speeds up to AC3000. Dedicated backhaul and LAN ports offer mesh flexibility so you can get the exact setup you're looking for. Best Wi-Fi 6 mesh: Netgear Nighthawk MK62 mesh Wi-Fi system Want Wi-Fi 6 performance AND a mesh network? This pack includes an AX1800 router and satellite, good for 3,000 square feet and many users. Ethernet ports on the main router and satellite allow for wired backhaul if you want the best performance possible, and you can also connect wired devices. Netgear Nighthawk RAX120 Thanks to Wi-Fi 6, this router offers four times the data capacity of 802.11ac tech. It has both 2.4GHz and 5GHz radios with combined speeds up to AX6000, ideal for large households with plenty of users. Connect all your devices (including wired devices thanks to five LAN ports) and see consistent speed, no matter the task. Our pick Any of the above routers will deliver a steady stream on wireless internet. However, if you're still wondering exactly where to start, we suggest going with either the Nighthawk R6700 for the average household that doesn't need Wi-Fi 6 or advanced features, or the Nighthawk RAX50 if you're willing to spend a bit more for the future. These are both great routers, though the latter will likely be better for people with many users in one home or building thanks to higher theoretical AX5400 speeds across 2.4GHz and 5GHz radios. But even if your house isn't packed with people all vying for streaming and gaming bandwidth, these routers should be sufficient and won't break the bank. If you're interested in upgrading to Wi-Fi 6, something like Netgear's Nighthawk RAX120 makes a lot of sense. It's expensive, but it'll set you up for the future as more and more devices move to the latest standard. And if you'd like to combine Wi-Fi 6 and mesh networking, the Netgear Nighthawk MK62 is the way to go.

Today almost every home and small  office has a local network, and an Internet connection. The home network or small office network enables multiple devices e.g. PCs, tablets etc to connect to each other, and also to connect to the internet. In this tutorial you will learn how you to build and setup a home or small office network and connect it to the Internet. Choosing a Wired or Wireless Network Do You Build a wired or Wireless Network? Early (pre 2008) home networks were predominately wired networks. Wired networks use Ethernet over UTP cable and tend to be faster than wireless networks, which is an important consideration if you are a gamer. The simple wired home network diagram below shows a minimum setup with a switch and broadband router. Wired Network Advantages Fast typically 100 Mbps to 10 Gbps Secure and reliable. Wired Network Dis-Advantages Doesn’t work with devices that don’t have an Ethernet port e.g. tablets and smart phones. Not so easy and fast to setup as it requires running cables. However Home plug or powerline adapters can be used instead. Not so easy for visitors and mobile devices (laptops) to connect to. Main Uses Used for network backbone i.e. connecting between router, network switches and wireless access points on different levels (floors). Home Wireless Networks Wireless networks use Wi-Fi. and are quick and easy to install, but are generally slower than wired networks. Wireless Network Advantages Easy to setup from an end user perspective. Allows easy access to smart phones, Tablets and mobile devices. No cables to run. Wireless Network Dis-Advantages Not as Secure as wired networks without proper configuration. and easy to setup insecurely. Not so as fast as wired networks. Not as reliable as wired networks. Main Uses Connecting peripheral devices like computers ,smart phone, tablets etc. Most home networks will use a mixture of wired and wireless. Setting up a Home Network -Components and Structure Today however most home and small home office networks will use a wireless network or mixed network, as most people use Smart phones, and tablets which don’t have Ethernet support. The main components required to build a typical home/small office network are: Router or Wireless router – Connects the network to the Internet. Wireless Access Point – Used to Connect Wi-Fi equipped devices to the network. Ethernet HUB or Switch -Used to Connect Ethernet equipped devices. Cable cat 5, cat5e or cat 6 with RJ45 connectors. Telephone Cable with RJ 10 connectors. Broadband Filters. The home network diagram below shows the structure of a typical small home network For most home networks the Wireless Router or Hub which connects the network to the Internet will be the main component of the home or small office network, and in many cases the only component. The Wireless router usually incorporates a Wireless access point,Ethernet switch, DSL modem and Router in a single box. This short video shows how to use a Wireless Home Hub ( BT) or router to create a home network that is connected to the Internet. DSL Modem– converts digital signals into analogue signals that are suitable for sending over a telephone line. It is usually built into the Internet/broadband router and is not normally purchased as a separate component. DSL/Broadband Filter– Used to filter out DSL signals from telephone signals so that you can access the internet and use the telephone simultaneously. Wireless Router Location The Wireless router will need to connect to the telephone line, cable or fibre network access point in your home. Therefore most people locate the Wireless router near to the main telephone socket. However you can usually change the location by using telephone extension cables or longer WAN cables. Note: WAN cables use the same connectors (RJ45) and cables as Ethernet cables. Because the Wireless Router provides the Wireless access point then you should place it in a central location, if possible, to get the best wireless reception. Don’t Hide it in a cupboard Install it behind the sofa install next to motors,microwaves,cordless telephones Testing Your Wireless Signal The easiest way of testing you signal strength in various locations is to use the inSSIDer Wi-Fi checker which is an App that you can install on your Android Tablet or phone. The general idea is to place the Wireless router in its preferred location and then move around the house with the inSSIDer Wi-Fi checker, and check the signal strength, and then adjust the location if necessary. Extending Your Home Network In large homes/offices it may not be possible to connect all devices directly to the Wireless router and so you will need to purchase additional networking components. You can extend your home network by: extending your Wi-Fi coverage by installing additional Wireless Access Points or a more powerful access point. or you can extend the Wired network by running cables into other rooms or using your power cables by installing home plug adapters. See How to extend a Home Network Home Router Setup To administer the router you access it via a web browser, and login using a username and password. Before you allow devices to connect to your home network you should make some basic changes to the default setup parameters of your router. The two important one are the SSID used to access the Router and the router admin password as the default username/passwords are well known, and published on the Internet. . Connecting Wi-Fi Devices The standard way of connecting a Wi-fi device to a Wi-fi network is the connect to the network and enter the password when prompted. However most modern Wi-Fi routers/hubs support a feature called WPS ( Wi-fi protected setup). Which usually involves pressing a button on the wi_fi router and a corresponding WPS connection button on the Device. The devices then connect without requiring you to enter a password. Home Network IP Addresses All of your devices will need an IP address. This is provided automatically by a service called DHCP which, by default, is provided by the home router. IP address provided by the DHCP server are known as dynamic address as they can change. You can also assign addresses manually, and these are known as static addresses. Static Addresses are not normally assigned but are often required when using Port forwarding. Additionally the addresses used on your home network are known as internal addresses. When you connect to the Internet your device will use an external IP address. This address is the IP address of the router/hub. See Internal vs external IP addresses for a more detailed explanation. Finding Your DNS, IP and MAC Addresses You may need to find out what DNS servers you are using or the IP or MAC address of: Your Home Router. Your own computer/tablet/phone The main tool you use is the ipconfig (windows) or ifconfig (linux) tool. The screen shot below shows the ipconfig command use with the /all switch. i.e. ipconfig/all Your home router is your gateway to the Internet. When viewing your configuration some devices refer to it as the default router whereas other use the term default gateway. In the screen shot above it is 192.168.1.254 Splitting Your Home Network You may find the need to split a home network for security reasons. This is especially true in small business networks like restaurants etc were customers are also given access to the network. The easiest and most common method is to use VLANs. Firewall Configuration on Home Networks A Firewall functions like a router, and generally what you use on small networks is firewall/NAT router combination in which a single device acts as a NAT router and firewall. A firewall protects your home or small business network computers and devices from intruders on the Internet. It effectively acts like a one way digital gate blocking access to your network from devices on the Internet, but at the same time allowing devices on your network to connect to devices on the Internet. (schematic diagram below) For small home/office networks the firewall is built into, and is part of, the router that connects to the Internet. Generally there is no configuration required as the default behaviour is only to allow connections from the local network to the Internet, and not from the Internet to the home network. However if you do require devices on the Internet to connect into your network (often required by gamers) then you can configure port forwarding. You may also want or need to use dynamic DNS- see What is Dynamic DNS ?  and Why Use Dynamic DNS Services? Checking Network and Internet Speeds On any network the speed is restricted by the slowest component. A computer with a Gigabit network card talking to a computer with a 100Mbit/s network card is restricted to 100Mbit/s. Shared devices like switches and Wireless access points are network choke points just like traffic lights and roundabouts on a road. LAN Speed test is a very useful tool for testing your local network speeds. For Internet speeds you can use online speed test sites. Home Network and Internet Connection Problems You will invariably have connection problems from time to time. In my experience most problems are easily diagnosed and fixed with a little patience and perseverance. Having a good understanding of how your network fits together, and works is essential for successful troubleshooting. Author Nerdcore Computers
