Jargon Decoder: What does "CPU" actually mean?
The CPU (Central Processing Unit) is the brain of your computer. It processes instructions, performs calculations, and controls how quickly your programs, games, and applications run.
Think of it as the engine powering your computer. A faulty or overheating CPU can cause slow performance, freezing, unexpected shutdowns, crashes, or even prevent your computer from starting properly.
