About this MCQ
This Hard Operating Systems question asks: What is the function or purpose of Virtual memory? The correct choice is B. A memory management technique that gives an application the illusion of a large, continuous memory space using disk storage.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Operating Systems items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Operating Systems so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Operating Systems item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. The smallest unit of execution within a process that can be scheduled independently.
Why not A: “The smallest unit of execution within a process that can be scheduled independently.” does not fit this question. The answer is A memory management technique that gives an application the illusion of a large, continuous memory space using disk storage..
- B. A memory management technique that gives an application the illusion of a large, continuous memory space using disk storage. ✓
- C. The process of storing the state of a running process so another process can be resumed later.
Why not C: “The process of storing the state of a running process so another process can be resumed later.” does not fit this question. The answer is A memory management technique that gives an application the illusion of a large, continuous memory space using disk storage..
- D. A synchronization variable used to control access to shared resources by multiple processes.
Why not D: “A synchronization variable used to control access to shared resources by multiple processes.” does not fit this question. The answer is A memory management technique that gives an application the illusion of a large, continuous memory space using disk storage..
Correct answer
B. A memory management technique that gives an application the illusion of a large, continuous memory space using disk storage.
