Paging

Paging: 

Paging is a technique in which the main memory of computer system is organized in the form of equal sized blocks called pages.

Page table:  Where the address of occupied pages of physical memory are stored.

Paging enables the operating system to obtain data from the physical memory location without specifying lengthy memory address in the instruction. In this technique, the virtual address is used to map the physical address of the data. The length of virtual address is specified in the instruction and is smaller than physical address of the data. It consists of two different numbers, first number is the address of page called virtual page in the page table and the second number is the offset value of the actual data in the page.
