CPU - The Brain of the Computer in Computer Basics
The CPU (Central Processing Unit) is the "brain" of the computer. It reads instructions from programs and makes decisions about what to do. Every single action your computer performs—opening files, running games, playing videos—is controlled by the CPU.
The CPU works by reading instructions one at a time and executing them super fast. Modern CPUs can do billions of instructions every single second! When you click a game, the CPU is working millions of times to calculate graphics, sound, and player movements.
CPU speed is measured in GHz (Gigahertz), which means billions of operations per second. A 2 GHz CPU does 2 billion operations per second, and a 4 GHz CPU does 4 billion. Faster CPUs make games smoother and programs more responsive.
Many modern CPUs have multiple "cores." A dual-core CPU has 2 cores and can run 2 programs simultaneously. Processors with 4, 8, or 16 cores can do many things at once, making your computer feel faster when running multiple programs.
