Use of instruction register and program counter:

Q. What is the use of instruction register (IR) and program counter (PC)?

Ans: The instruction register (IR) holds the instruction that is at present being executed .Its output is available to the control circuits which produce the timing signals that control the various processing elements. The program counters PC which is used to keep track of the execution of the program. It has the memory address of the next instruction to be fetched and to execute.
