Question:

1. What are instruction cycle, machine cycle and clock cycle?

 

2. Is there a fixed value for the instruction cycle? why?

Because the time required to execute each instruction in the computer varies greatly, in order to improve the operating efficiency of the CPU, even in a synchronously controlled machine, the instruction cycle length of different instructions is not consistent, that is, the instruction cycle is not for different instructions. A fixed value.
