What term describes the following? a special-purpose CPU register used to store the intermediate results of arithmetic and logic operations.
Difficulty: Medium
About this MCQ
This Medium Computer Architecture MCQ checks one syllabus fact.
The question is: “What term describes the following? a special-purpose CPU register used to store the intermediate results of arithmetic and logic operations.”
The accepted answer is C. Accumulator. Accumulator is the fact required by “What term describes the following? a special-purpose CPU register used to store the intermediate results of arithmetic and logic operations.” (option C). Option A (“Flynn's taxonomy”) does not match the stem; it is a near-miss used to catch incomplete recall of Accumulator. Option B (“Data path”) does not match the stem; it is a near-miss used to catch incomplete recall of Accumulator. Remaining alternatives (Instruction cycle) fall outside the same rule and should be eliminated once Accumulator 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. Flynn's taxonomy
Why not A: “Flynn's taxonomy” is not correct. The accepted answer is C. Accumulator. Accumulator is the fact required by “What term describes the following? a special-purpose CPU register used to store the intermediate results of arithmetic and logic operations.” (
- B. Data path
Why not B: “Data path” is not correct. The accepted answer is C. Accumulator. Accumulator is the fact required by “What term describes the following? a special-purpose CPU register used to store the intermediate results of arithmetic and logic operations.” (
- C. Accumulator ✓
- D. Instruction cycle
Why not D: “Instruction cycle” is not correct. The accepted answer is C. Accumulator. Accumulator is the fact required by “What term describes the following? a special-purpose CPU register used to store the intermediate results of arithmetic and logic operations.” (
Correct answer
C. Accumulator
