What is the name for the inefficient use of memory that occurs when free space is broken into small, scattered blocks?
Difficulty: Medium
About this MCQ
This Medium Operating Systems MCQ checks one syllabus fact.
The question is: “What is the name for the inefficient use of memory that occurs when free space is broken into small, scattered blocks?”
The accepted answer is B. Memory fragmentation. Memory fragmentation is the fact required by “What is the name for the inefficient use of memory that occurs when free space is broken into small, scattered blocks” (option B). Option A (“Round robin scheduling”) does not match the stem; it is a near-miss used to catch incomplete recall of Memory fragmentation. Option C (“Mutex”) does not match the stem; it is a near-miss used to catch incomplete recall of Memory fragmentation. Remaining alternatives (Memory segmentation) fall outside the same rule and should be eliminated once Memory fragmentation 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.
- A. Round robin scheduling
Why not A: “Round robin scheduling” is not correct. The accepted answer is B. Memory fragmentation. Memory fragmentation is the fact required by “What is the name for the inefficient use of memory that occurs when free space is broken into small, scattered blocks” (option B). Opt
- B. Memory fragmentation ✓
- C. Mutex
Why not C: “Mutex” is not correct. The accepted answer is B. Memory fragmentation. Memory fragmentation is the fact required by “What is the name for the inefficient use of memory that occurs when free space is broken into small, scattered blocks” (option B). Opt
- D. Memory segmentation
Why not D: “Memory segmentation” is not correct. The accepted answer is B. Memory fragmentation. Memory fragmentation is the fact required by “What is the name for the inefficient use of memory that occurs when free space is broken into small, scattered blocks” (option B). Opt
Correct answer
