The Central Processing Unit (CPU) is often referred to as the brain of the computer because it performs the essential tasks of executing instructions and processing data. It is responsible for making decisions based on the input it receives and carries out various arithmetic and logical operations. The CPU interprets and processes commands provided by software applications and the operating system, thereby playing a crucial role in driving the functionality of the entire system.

This ability to make decisions and manage inputs allows the CPU to coordinate the activities of other hardware components and ensures that the computer operates efficiently. By processing data and controlling other components, the CPU allows for the execution of complex operations and supports user interactions with software applications, making it a fundamental part of computing.
