Control Unit

Control Unit: A component of the central processing unit (CPU) in a computer that directs the operation of the processor. It controls the flow of data within the CPU and between the CPU and other components of the computer by coordinating and executing instruction sequences, managing the timing of operations, and interpreting the computer’s program instructions. Essentially, it acts as the ‘traffic cop’ for data and instructions within the computer system.
