An instruction cycle (sometimes called fetch-and-execute cycle, fetch-decode-execute cycle, या FDX) is the basic operation cycle of a computer. It is the process द्वारा which a computer retrieves a program instruction from its memory, determines what actions the instruction requires, and carries out those actions. This cycle is repeated continuously द्वारा the central processing unit (CPU), from bootup to when the computer is shut down.
