Which memory is the fastest in a modern computer?
Difficulty: Medium
About this MCQ
This Medium Memory & Storage MCQ checks one syllabus fact.
The question is: “Which memory is the fastest in a modern computer?”
The accepted answer is B. CPU Register. CPU Register is the person, body, or term that satisfies “Which memory is the fastest in a modern computer” (option B). Option A (“RAM”) does not match the stem; it is a near-miss used to catch incomplete recall of CPU Register. Option C (“Hard Disk”) does not match the stem; it is a near-miss used to catch incomplete recall of CPU Register. Remaining alternatives (Cache) fall outside the same rule and should be eliminated once CPU Register is identified. Memory & Storage questions of this type reward precise definitions rather than approximate associations. Memory & Storage recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
- A. RAM
Why not A: “RAM” is not correct. The accepted answer is B. CPU Register. CPU Register is the person, body, or term that satisfies “Which memory is the fastest in a modern computer” (option B). Option A (“RAM”) does not match the stem; it is a near-miss
- B. CPU Register ✓
- C. Hard Disk
Why not C: “Hard Disk” is not correct. The accepted answer is B. CPU Register. CPU Register is the person, body, or term that satisfies “Which memory is the fastest in a modern computer” (option B). Option A (“RAM”) does not match the stem; it is a near-miss
- D. Cache
Why not D: “Cache” is not correct. The accepted answer is B. CPU Register. CPU Register is the person, body, or term that satisfies “Which memory is the fastest in a modern computer” (option B). Option A (“RAM”) does not match the stem; it is a near-miss
