A CPU (Central Processing Unit) is the computer's brain, a small silicon chip on the motherboard that executes instructions, performs arithmetic and logical operations, and manages input/output functions for the entire system. It acts as the primary computational unit, processing data, running operating systems and applications, and controlling the flow of information between other hardware components. The speed and efficiency of the CPU directly impact a computer's overall performance.

Core Functions

Executing Instructions: The CPU follows instructions from computer programs, retrieving them from memory, decoding them, and then executing them in a cycle known as the fetch-decode-execute cycle.

Processing Data: It handles all types of data, transforming input into information and output by performing calculations and logical comparisons.

Controlling Operations: The CPU serves as the central control unit, regulating the operations of other hardware components and allocating computing resources.
