FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Virtual memory is a mechanism used to manage memory using hardware and software. It is a part of the secondary storage that gives the user an illusion that it is a part of the main memory. It helps in running multiple applications with low main memory and increases the degree of multiprogramming in systems.

Detailed explanation-2: -Virtual memory is a common technique used in a computer’s operating system (OS). Virtual memory uses both hardware and software to enable a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM) to disk storage.

Detailed explanation-3: -Secondary storage might include hard disk drives (HDDs), solid-state drives (SSDs), optical disks, USB flash drives, floppy disks or other devices.

Detailed explanation-4: -Secondary memory is computer memory that is non-volatile, persistent and not immediately accessible by a computer or processor. It allows users to store data and information that can be retrieved, transmitted, and used by apps and services quickly and easily.
