What are pages in Operating System?
  • A page, also known as a memory page or virtual page, is a continuous block of virtual memory with a defined length that is described by a single entry in the page table. In a virtual memory operating system, it is the smallest unit of data for memory management.
  • A page frame is the smallest fixed-length contiguous unit of physical memory into which the operating system maps memory pages.
  • Paging or swapping is the process of moving pages from main memory to an auxiliary store, such as a hard disc drive.
  • Paging is a memory management technique that avoids the requirement for contiguous physical memory allocation.
