What does CPU stand for?

The term CPU stands for Central Processing Unit, which is the primary component of a computer that performs most of the processing inside the computer. It is often referred to as the brain of the computer because it carries out instructions from programs and manages the operations of other hardware components.

The CPU handles a variety of tasks, such as arithmetic calculations, logical operations, and control of input/output devices. It processes data stored in memory and executes instructions that enable users to run software applications. The Central Processing Unit is essential for the functionality of a computer system, making it a foundational piece of modern technology.

Other options listed do not reflect the standard terminology used in computing. "Computer Performance Utility," for instance, suggests software dealing with performance metrics rather than a central hardware unit. "Core Processing Unit" could mislead, as cores refer to multiple processing units within a single physical CPU but do not encompass the entire CPU itself. "Command Performance Unit" is not a recognized term in the context of computer hardware.
