What is paging explain with example?

In Operating Systems, Paging is a storage mechanism used to retrieve processes from the secondary storage into the main memory in the form of pages. The main idea behind the paging is to divide each process in the form of pages. The main memory will also be divided in the form of frames.

Why do we need paging?

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 and swapping?

Swapping occurs when whole process is transferred to disk. Paging occurs when some part of process is transferres to disk. In this process is swapped temporarily from main memory to secondary memory. In this the contiguous block of memory is made non-contiguous but of fixed size called frame or pages.
