COMPUTER FUNDAMENTALS

Detailed explanation-1: -When a computer uses up its available RAM, pages not in use are transferred to the hard drive using a swap file. 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.

Detailed explanation-2: -When a computer reaches its RAM limits, it transfers any currently unused pages into the part of its hard drive used for virtual memory. The computer performs this process using a swap file, a designated space within its hard drive for extending the virtual memory of the computer’s RAM.

Detailed explanation-3: -Where is the data stored when it is in virtual memory? It is stored on an area of a secondary storage device e.g. hard disk drive. Describe how a computer uses virtual memory. A process running on the computer may need to store data in the physical memory.

Detailed explanation-4: -Paging is the name given to the process of storing and retrieving data between a HDD/SSD and RAM. Pages of data are transferred between RAM and virtual memory when needed. Paging is essential for virtual memory to work.
