What is the role of control unit in computer?
The control unit is one of the most important parts of a microprocessor for the reason that it is in charge of the entire process, that is the machine cycle. The CPU deals with each instruction it is given in a series of steps. Each step is repeated for each instruction. This series of steps is called the machine cycle. It involves:fetching an instruction from memory;decoding the instruction;transferring the data;executing the instruction.The control unit makes sure that all of those actions are carried out. It also manages all the other components on the CPU.
