Paging in Operating Systems: A Comprehensive Guide
Paging in Operating Systems: A Comprehensive Guide S Paging is a method of gaining access to data more quickly. When a program requires a page, it is available in the main memory because the OS copies a set number of pages from the storage device into the main memory. Paging permits a process’s physical address space to be noncontiguous. Paging refers to a memory management strategy that does away with the need for the allocation of contiguous physical memory. What is Paging in the OS? Paging is a storage mechanism used in OS to retrieve processes from secondary storage to the main memory as pages. The primary concept behind paging is to break each process into individual pages. Thus the primary memory would also be separated into frames. One page of the process must be saved in one of the given memory frames. These pages can be stored in various memory locations, but finding contiguous frames/holes is always the main goal. Process pages are usually only b...
