About this MCQ

This Hard Operating Systems MCQ checks one syllabus fact.

The question is: “What is the function or purpose of Virtual memory?”

The accepted answer is B. A memory management technique that gives an application the illusion of a large, continuous memory space using disk storage.. A memory management technique that gives an application the illusion of a large continuous memory space using disk storage is the fact required by What is the function or purpose of Virtual memory option B Option A The smallest unit of execution within a process that can be scheduled independently does not match the stem it is a near-miss used to catch incomplete recall of A memory management technique that gives an application the illusion of a large continuous memory space using disk storage Option C The process of storing the state of a running process so another process can be resumed later does not match the stem it is a near-miss used to catch incomplete recall of A memory.

A. The smallest unit of execution within a process that can be scheduled independently.
