An instruction cycle (also known as the fetch -- decode -- execute cycle or the fetch - execute cycle) is the basic operational process of a computer. It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction dictates, and carries out those actions. This cycle is repeated continuously by a computer 's central processing unit (CPU), from boot - up to when the computer is shut down.
