MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In computing, virtual memory, or virtual storage is a memory management technique that provides an “idealized abstraction of the storage resources that are actually available on a given machine” which “creates the illusion to users of a very large (main) memory".

Detailed explanation-2: -Q. Which is the memory that works on time sharing principle in order to create an illusion of infinite memory space? Notes: Virtual memory is that uses hardware and software to allow a computer to compensate for physical memory shortages by temporarily transferring data from random access memory (RAM) to disk storage.

Detailed explanation-3: -Sometimes called “working memory” (see point 4), short-term memory is used to temporarily store and retrieve – within less than a minute – the information being processed. It allows us to remember, for example, a name, a number or a list of elements.

Detailed explanation-4: -Virtual memory is a feature of an operating system that enables a computer to be able to compensate for shortages of physical memory by transferring pages of data from random access memory to disk storage. This process is done temporarily and is designed to work as a combination of RAM and space on the hard disk.

Detailed explanation-5: -Virtual memory is an illusion of an extremely large memory.
