What is paging?
Paging is a memory management scheme that authorizes the physical-address space of a process to be noncontiguous. Paging evades the considerable problem of fitting the varying-sized memory chunks onto the backing store, from which the majority of the previous memory-management schemes suffered.

The fragmentation problem suffered in the backing store is as well avoided for the reason that of its advantage over the previous methods, paging in its different forms is commonly used in most operating systems.
