Paging is a method of writing data to, and reading it from, secondary storage for use in primary storage, also known as main memory.

In a memory management system that takes advantage of paging, the OS reads data from secondary storage in blocks called pages, all of which have identical size.

What is paging and how it works?

Paging is used for faster access to data. When a program needs a page, it is available in the main memory as the OS copies a certain number of pages from your storage device to main memory. Paging allows the physical address space of a process to be noncontiguous.

What is paging in OS?

Paging technique plays an important role in implementing virtual memory. Paging is a memory management technique in which process address space is broken into blocks of the same size called pages (size is power of 2, between 512 bytes and 8192 bytes). The size of the process is measured in the number of pages.
