Difficulty: Easy
About this MCQ
This Easy Operating Systems MCQ checks one syllabus fact.
The question is: “Which concept is defined as follows: the ability of an operating system to execute multiple tasks or processes concurrently?”
The accepted answer is D. Multitasking. Multitasking is the person, body, or term that satisfies “Which concept is defined as follows: the ability of an operating system to execute multiple tasks or processes concurrently” (option D). Option A (“Device driver”) does not match the stem; it is a near-miss used to catch incomplete recall of Multitasking. Option B (“Deadlock”) does not match the stem; it is a near-miss used to catch incomplete recall of Multitasking. Remaining alternatives (Paging) fall outside the same rule and should be eliminated once Multitasking 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.

Why not A: “Device driver” is not correct. The accepted answer is D. Multitasking. Multitasking is the person, body, or term that satisfies “Which concept is defined as follows: the ability of an operating system to execute multiple tasks or processes concurrentl
- B. Deadlock
Why not B: “Deadlock” is not correct. The accepted answer is D. Multitasking. Multitasking is the person, body, or term that satisfies “Which concept is defined as follows: the ability of an operating system to execute multiple tasks or processes concurrentl
- C. Paging
Why not C: “Paging” is not correct. The accepted answer is D. Multitasking. Multitasking is the person, body, or term that satisfies “Which concept is defined as follows: the ability of an operating system to execute multiple tasks or processes concurrentl
- D. Multitasking ✓
Correct answer
D. Multitasking
Explanation
Multitasking is the person, body, or term that satisfies “Which concept is defined as follows: the ability of an operating system to execute multiple tasks or processes concurrently” (option D). Option A (“Device driver”) does not match the stem; it is a near-miss used to catch incomplete recall of Multitasking. Option B (“Deadlock”) does not match the stem; it is a near-miss used to catch incomplete recall of Multitasking. Remaining alternatives (Paging) fall outside the same rule and should be eliminated once Multitasking is identified. Operating Systems questions of this type reward precise definitions rather than approximate associations.
