The CPU (central processing unit) is the computer's "brain": its main function is to execute program instructions. It repeatedly fetches instructions from memory, decodes them, and performs the required actions (arithmetic/logic operations, data moves, and control tasks). The CPU’s control unit directs the process, the ALU does calculations and logical tests, and registers hold immediate data and instructions.
