Explanation of Solution

Cycle time of a processor

  • A clock cycle or simply a cycle is a single electronic pulse of a central processing unit (CPU).
  • A CPU can perform a basic operation such as fetching an instruction, accessing memory or writing data during each cycle.
  • Since only simple commands can be performed during each cycle, most CPU processes require multiple clock cycles.
  • The frequency of a processor is determined by clock cycles per second.
  • The frequency of a processor is also known as processor’s clock speed.
