Paging

In computer operating systems, paging is one of the memory management schemes by which a computer stores and retrieves data from the secondary storage for use in main memory. In the paging memory-management scheme, the operating system retrieves data from secondary storage in same-size blocks called pages. The main advantage of paging over memory segmentation is that it allows the physical address space of a process to be noncontiguous. Before paging came into use, systems had to fit whole programs or their whole segments into storage contiguously, which caused various storage and fragmentation problems.Paging is an important part of virtual memory implementation in most contemporary general-purpose operating systems, allowing them to use secondary storage for data that does not fit into physical random-access memory (RAM).
