The function of the control unit is to supervise, monitor, coordinateds, control, and manage the various operations of a digital system. The control unit directs and coordinates the entire computer system in carrying out program instructions. It does not execute the instructions itself but instead directs other parts of the computer system to do so. The control unit supervises the flow of information between various units. It regulates the operations of the computer and enables it to communicate with operator and other devices in the system.
