  2. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    The required disk space may be easily allocated on systems with more recent specifications (i.e. a system with 3 GB of memory having a 6 GB fixed-size page file on a 750 GB disk drive, or a system with 6 GB of memory and a 16 GB fixed-size page file and 2 TB of disk space).

  3. Page (computer memory) - Wikipedia

    en.wikipedia.org/wiki/Page_(computer_memory)

    A system with a smaller page size uses more pages, requiring a page table that occupies more space. For example, if a 2 32 virtual address space is mapped to 4 KiB (2 12 bytes) pages, the number of virtual pages is 2 20 = (2 32 / 2 12). However, if the page size is increased to 32 KiB (2 15 bytes), only 2 17 pages are required. A multi-level ...

  4. Page cache - Wikipedia

    en.wikipedia.org/wiki/Page_cache

    When a file write occurs, the cached page for the particular block is looked up. If it is already found in the page cache, the write is done to that page in the main memory. If it is not found in the page cache, then, when the write perfectly falls on page size boundaries, the page is not even read from disk, but allocated and immediately ...

  5. Page replacement algorithm - Wikipedia

    en.wikipedia.org/wiki/Page_replacement_algorithm

    The unified page cache operates on units of the smallest page size supported by the CPU (4 KiB in ARMv8, x86 and x86-64) with some pages of the next larger size (2 MiB in x86-64) called "huge pages" by Linux. The pages in the page cache are divided in an "active" set and an "inactive" set.

  6. Page table - Wikipedia

    In this case the page is paged out to a secondary store located on a medium such as a hard disk drive (this secondary store, or "backing store", is often called a swap partition if it is a disk partition, or a swap file, swapfile or page file if it is a file). When this happens the page needs to be taken from disk and put back into physical memory.

  8. Physical Address Extension - Wikipedia

    en.wikipedia.org/wiki/Physical_Address_Extension

    The entries in the page directory have an additional flag in bit 7, named PS (for page size). If the system has set this bit to 1, the page directory entry does not point to a page table but to a single, large 4 MB page (Page Size Extension).

  9. Pagination - Wikipedia

    en.wikipedia.org/wiki/Pagination

    Pagination, also known as paging, is the process of dividing a document into discrete pages, either electronic pages or printed pages.. In reference to books produced without a computer, pagination can mean the consecutive page numbering to indicate the proper order of the pages, which was rarely found in documents pre-dating 1500, and only became common practice c. 1550, when it replaced ...
