The full form of CPU is Central Processing Unit. The CPU is known as the brain of the computer. It performs all the processing tasks of a computer system. It takes input, processes it, and gives output. Every command that you give to a computer—like opening a file, running an application, or doing a calculation—is handled by the CPU.

Main Functions of CPU

Fetch: Collects data or instructions from memory.
Decode: Understands what the instructions mean.
Execute: Performs the task or command.
