Detailed explanation-2: -A control unit, or CU, is circuitry within a computer’s processor that directs operations. It instructs the memory, logic unit, and both output and input devices of the computer on how to respond to the program’s instructions.
Detailed explanation-3: -The large program that controls how the CPU communicates with other hardware components is the operating system.
Detailed explanation-4: -A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.). Most computer resources are managed by the CU.
Detailed explanation-5: -The Control Unit is a processor which is a hardware device.
