Question

which one of the following statements is true regarding the fetch - execute cycle?
each step of the fetch - execute cycle is performed once per minute
the fetch - execute cycle is only carried out when a user types in input
the order of steps in the fetch - execute cycle is fetch - execute - store - decode.
the device responsible for performing the fetch - execute cycle is the cpu

Explanation:

The fetch - execute cycle is a fundamental operation of the CPU. It fetches instructions from memory, decodes them, and then executes them. It is not performed once per minute, nor is it only carried out when user input is typed. The correct order of steps is fetch - decode - execute - store (not as stated in one of the options). The CPU is the device that performs the fetch - execute cycle.

Answer:

The device responsible for performing the fetch - execute cycle is the CPU.
