Difficulty: Hard
About this MCQ
This Hard Memory & Storage MCQ checks one syllabus fact.
The question is: “A condition where a system spends most of its time swapping data between memory and disk rather than executing useful work. What is this concept called?”
The accepted answer is A. Thrashing. “A condition where a system spends most of its time swapping data between memory and disk rather than executing useful work. What is this concept called” is answered by Thrashing (option A). Option B (“Tertiary storage”) does not match the stem; it is a near-miss used to catch incomplete recall of Thrashing. Option C (“Solid-state drive (SSD)”) does not match the stem; it is a near-miss used to catch incomplete recall of Thrashing. Remaining alternatives (NVMe) fall outside the same rule and should be eliminated once Thrashing 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.
