What is known as "the brain" of the Computer?

The Central Processing Unit (CPU) is known as the brain of the computer because it is responsible for executing instructions, performing calculations, and managing the flow of data within the computer system. It acts as a control unit by coordinating and directing the activities of other hardware devices and components. Similar to how the human brain controls all the functions of the body, the CPU is the core component that carries out all the essential tasks required for the computer to function.
