Identify the correct concept described as: another term for the sequence of fetching, decoding, and executing a single CPU instruction.
Difficulty: Medium
About this MCQ
This Medium Computer Architecture MCQ checks one syllabus fact.
The question is: “Identify the correct concept described as: another term for the sequence of fetching, decoding, and executing a single CPU instruction.”
The accepted answer is A. Instruction cycle. “Identify the correct concept described as: another term for the sequence of fetching, decoding, and executing a single CPU instruction.” is answered by Instruction cycle (option A). Option B (“Data path”) does not match the stem; it is a near-miss used to catch incomplete recall of Instruction cycle. Option C (“Program counter”) does not match the stem; it is a near-miss used to catch incomplete recall of Instruction cycle. Remaining alternatives (Accumulator) fall outside the same rule and should be eliminated once Instruction 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. Instruction cycle ✓
- B. Data path
Why not B: “Data path” is not correct. The accepted answer is A. Instruction cycle. “Identify the correct concept described as: another term for the sequence of fetching, decoding, and executing a single CPU instruction.” is answered by Instruction cycle (option A
- C. Program counter
Why not C: “Program counter” is not correct. The accepted answer is A. Instruction cycle. “Identify the correct concept described as: another term for the sequence of fetching, decoding, and executing a single CPU instruction.” is answered by Instruction cycle (option A
- D. Accumulator
Why not D: “Accumulator” is not correct. The accepted answer is A. Instruction cycle. “Identify the correct concept described as: another term for the sequence of fetching, decoding, and executing a single CPU instruction.” is answered by Instruction cycle (option A
