What is the primary function of the Central Processing Unit (CPU)?

The primary function of the Central Processing Unit (CPU) is to perform calculations and data processing. The CPU is often referred to as the brain of the computer because it executes instructions from programs, processes data, and carries out arithmetic and logical operations. It interprets and executes commands received from the computer's hardware and software, allowing the system to function effectively.

This processing capability is essential for running applications, performing computations, and managing various tasks within the operating system. The importance of the CPU in a computer system cannot be overstated, as it is crucial for the overall speed and functionality of the machine.

While other components and functionalities, such as storage and graphical output, are vital to computer operations, they serve different roles. The CPU's unique capability to handle data processing and execute program instructions differentiates it from other components.
