<P> In computer operating systems , paging is a memory management scheme by which a computer stores and retrieves data from secondary storage for use in main memory . In this scheme , the operating system retrieves data from secondary storage in same - size blocks called pages . Paging is an important part of virtual memory implementations in modern operating systems , using secondary storage to let programs exceed the size of available physical memory . </P>
