What is the function of a CPU in a computer?

The central processing unit (CPU) is often referred to as the "brain" of the computer. It performs the essential calculations and instructions that allow the computer to function. The CPU carries out tasks such as executing program instructions, performing arithmetic and logic operations, and managing input/output operations. It also controls the operations of other hardware components within the computer. In short, the CPU is responsible for processing and executing instructions, making it a crucial component in the overall functioning of a computer.

Understanding the role of the CPU is fundamental to comprehending the inner workings of computer hardware and its significance in technology.
