Paging operating system system code example

Example: paging in os

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.One page of the process is to be 
stored in one of the frames of the memory. 
The pages can be stored at the different locations 
of the memory but the priority is always to
find the contiguous frames or holes
