Question

which of the following statements are true regarding the fetch - execute cycle? select 3 options. the order of steps in the fetch - execute cycle is fetch - decode - execute - store. fetch refers to saving output to the hard drive. the device responsible for performing the fetch - execute cycle is the cpu. each step of the fetch - execute cycle is performed for each instruction. the fetch - execute cycle is only carried out when a user types in input.

Explanation:

1. The correct order of the fetch - execute cycle is fetch - decode - execute - store, so the first option is true.
2. Fetch refers to retrieving an instruction from memory, not saving output to the hard drive, so the second option is false.
3. The CPU is responsible for performing the fetch - execute cycle, so the third option is true.
4. Each step of the fetch - execute cycle is performed for each instruction, so the fourth option is true.
5. The fetch - execute cycle is continuously carried out for program execution and not just when user types in input, so the fifth option is false.

Answer:

The true statements are:

• The order of steps in the fetch - execute cycle is fetch - decode - execute - store.
• The device responsible for performing the fetch - execute cycle is the CPU.
• Each step of the fetch - execute cycle is performed for each instruction.
