The time required for the fetching and execution of one simple machine instruction is

  • A.Delay time
  • B.CPU cycle
  • C.Real time
  • D.Seek time
  • E.None of the above

Answer: B

Correct answer: CPU cycle

The complete fetch–decode–execute sequence for one simple machine instruction is a CPU cycle (also called the machine or instruction cycle). Seek time is how long a disk arm takes to reach a track, and real time refers to processing that must keep pace with external events.
