NIMCET 2023 — Computer PYQ
NIMCET | Computer | 2023The time required for fetching and execution of one machine instruction is
Choose the correct answer:
- A.
Delay time
- B.
Seek time
- C.
Real time
- D.
CPU cycle
(Correct Answer)
CPU cycle
Explanation
The time required for fetching and execution of one machine instruction is called a CPU cycle.
Explanation:
• CPU cycle: This refers to the complete process of a CPU fetching an instruction from memory, decoding it, and then executing it.
Why other options are incorrect:
• Delay time: Delay time refers to the time spent waiting for data to be transferred between components, such as between the CPU and memory. It's a part of the overall CPU cycle but not the entire process.
• Seek time: Seek time is specifically related to accessing data on a hard disk. It's the time the disk head takes to move to the correct location on the disk. This is not relevant to the CPU's execution of instructions.
• Real time: Real time refers to a system that responds to events as they happen, with minimal time delay. It's not directly related to the execution of individual instructions on a CPU.
