ist two components with which the CPU works to execute program instructions. Memory Input and Output Devices Describe the role of the Control Unit in the fetch-decode-execute cycle. The control unit coordinates the actions of the computer. It sends out control signals to other parts of the CPU and to other components of the computer. State the function of the Program Counter. This holds the address of the next instruction to be fetched. State the function of the Memory Data Register ...
