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

The primary function of the Central Processing Unit (CPU) is to process instructions. The CPU is often referred to as the brain of the computer because it performs the essential calculations and logic operations necessary for executing programs. It interprets and carries out commands from the computer's software by accessing and manipulating data as per the instructions provided.

In this context, the CPU executes a variety of tasks, including arithmetic operations, logical comparisons, and control functions, all of which are critical for the proper functioning of computer applications and the operating system. This role is fundamental to the performance of a computer, as it directly affects how efficiently software runs and how quickly operations are completed.

While data storage, network management, and graphics display are important aspects of computer functionality, they fall under the responsibilities of other components within a computer system. For instance, memory devices are responsible for data storage, network interface cards manage network connections, and graphics processing units (GPUs) handle graphics rendering.
