CPUs (Central Processing Units)

A CPU, or Central Processing Unit, is the main brain of a computer that performs instructions to run programs. It processes data by fetching instructions from memory, decoding what to do, and executing tasks like calculations or moving information. The CPU's speed, measured in GHz, affects how quickly it can handle tasks. It also has cores, which are individual processing units, allowing it to perform multiple tasks simultaneously. Essentially, the CPU coordinates all operations within a computer, making everything from browsing the internet to gaming possible.
