Detailed explanation-1: -The control unit sends out a memory read signal, and the contents of the address 0000 are copied through the data bus to the memory data register (MDR). As the data fetched during the fetch stage is an instruction, it is copied into the instruction register (IR).
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 Central Processing Unit (CPU) is the primary component of a computer that acts as its “control center.” The CPU, also referred to as the “central” or “main” processor, is a complex set of electronic circuitry that runs the machine’s operating system and apps.
