FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A swap file is a space set aside on the hard drive to be used as the virtual memory extension for the computer’s RAM. When the swap file is needed, it is sent back to RAM using a process called page swapping. This system ensures the computer’s OS and applications do not run out of real memory.

Detailed explanation-2: -Therefore, Windows operating systems like adopting the virtual memory technology to increase computer’s memory capability. This technology will leave a part of hard disk space to act as memory.

Detailed explanation-3: -Virtual memory (also known as a page file) is essentially a block of space on your hard drive or solid state drive allocated by the OS to pretend to be RAM when your physical RAM runs short for actively running programs.

Detailed explanation-4: -Virtual memory provides virtual address mapping between applications and hardware memory. It provides many functions, including multitasking (multiple tasks executing at once on one CPU), allowing multiple processes to access the same shared library in memory, swapping, and other functions.

Detailed explanation-5: -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".
