What is the name for the basic operational process a CPU repeats to run instructions: fetching, decoding, and executing them?
Difficulty: Easy
About this MCQ
This Easy Computer Architecture MCQ checks one syllabus fact.
The question is: “What is the name for the basic operational process a CPU repeats to run instructions: fetching, decoding, and executing them?”
The accepted answer is B. Fetch-decode-execute cycle. Fetch-decode-execute cycle is the fact required by “What is the name for the basic operational process a CPU repeats to run instructions: fetching, decoding, and executing them” (option B). Option A (“Bus”) does not match the stem; it is a near-miss used to catch incomplete recall of Fetch-decode-execute cycle. Option C (“Parallel processing”) does not match the stem; it is a near-miss used to catch incomplete recall of Fetch-decode-execute cycle. Remaining alternatives (ALU) fall outside the same rule and should be eliminated once Fetch-decode-execute cycle is identified. Computer Architecture questions of this type reward precise definitions rather than approximate associations. Computer Architecture recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
- A. Bus
Why not A: “Bus” is not correct. The accepted answer is B. Fetch-decode-execute cycle. Fetch-decode-execute cycle is the fact required by “What is the name for the basic operational process a CPU repeats to run instructions: fetching, decoding, and executing them” (o
- B. Fetch-decode-execute cycle ✓
- C. Parallel processing
Why not C: “Parallel processing” is not correct. The accepted answer is B. Fetch-decode-execute cycle. Fetch-decode-execute cycle is the fact required by “What is the name for the basic operational process a CPU repeats to run instructions: fetching, decoding, and executing them” (o
- D. ALU
Why not D: “ALU” is not correct. The accepted answer is B. Fetch-decode-execute cycle. Fetch-decode-execute cycle is the fact required by “What is the name for the basic operational process a CPU repeats to run instructions: fetching, decoding, and executing them” (o
