When we talk about any operating system I happen to hear the term called paging. What is this actually? Is this term so important for operating system?
Paging is a very essential term used in operating system. There are lot of things to say about paging but to say in short about paging is paging refers to the transfer of pages of data between system's main memory and auxiliary memory.
In computer operating systems that have their main memory divided into pages, paging (sometimes called swapping) is a transfer of pages between main memory and an auxiliary store, such as hard disk drive.[1] Paging is an important part of virtual memory implementation in most contemporary general-purpose operating systems, allowing them to use disk storage for data that does not fit into physical RAM. Paging is usually implemented as architecture-specific code built into the kernel of the operating system.
A paging file is an area in the hard disk that windows uses as if it were RAM. Sometimes we call is swapping.
