Identify the correct concept described as: a small, high-speed memory layer that stores frequently accessed data to reduce access time.
Difficulty: Medium
About this MCQ
This Medium Memory & Storage MCQ checks one syllabus fact.
The question is: “Identify the correct concept described as: a small, high-speed memory layer that stores frequently accessed data to reduce access time.”
The accepted answer is D. Cache memory. “Identify the correct concept described as: a small, high-speed memory layer that stores frequently accessed data to reduce access time.” is answered by Cache memory (option D). Option A (“Secondary storage”) does not match the stem; it is a near-miss used to catch incomplete recall of Cache memory. Option B (“Memory buffer”) does not match the stem; it is a near-miss used to catch incomplete recall of Cache memory. Remaining alternatives (Magnetic storage) fall outside the same rule and should be eliminated once Cache memory 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.
