Difficulty: Hard
About this MCQ
This Hard Operating Systems MCQ checks one syllabus fact.
The question is: “What term describes the following? the OS component that decides which process runs on the CPU at any given time.”
The accepted answer is C. CPU scheduling. CPU scheduling is the fact required by “What term describes the following? the OS component that decides which process runs on the CPU at any given time.” (option C). Option A (“Thread”) does not match the stem; it is a near-miss used to catch incomplete recall of CPU scheduling. Option B (“Kernel”) does not match the stem; it is a near-miss used to catch incomplete recall of CPU scheduling. Remaining alternatives (Paging) fall outside the same rule and should be eliminated once CPU scheduling is identified. Operating Systems questions of this type reward precise definitions rather than approximate associations. Operating Systems recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
