What role does the Control Unit play in a computer?

The Control Unit is a critical component of the CPU (Central Processing Unit) that primarily directs the operation of the processor. It orchestrates the execution of instructions by fetching them from memory, decoding them, and sending signals to other parts of the computer to carry out the necessary operations. This includes controlling the sequence of operations and managing how data is processed within the CPU.

By coordinating the activities of the arithmetic logic unit (which performs calculations), the register file (which manages data storage), and the input/output systems, the Control Unit ensures that the processor performs its tasks efficiently and in the correct order. This central role makes it essential for maintaining the overall functionality of a computer system.
