    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 ...

  3. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    Memory paging. In computer operating systems, memory paging (or swapping on some Unix-like systems) is a memory management scheme by which a computer stores and retrieves data from secondary storage [a] for use in main memory. [citation needed] In this scheme, the operating system retrieves data from secondary storage in same-size blocks called ...

  5. Memory segmentation - Wikipedia

    en.wikipedia.org/wiki/Memory_segmentation

    Memory segmentation is an operating system memory management technique of dividing a computer 's primary memory into segments or sections. In a computer system using segmentation, a reference to a memory location includes a value that identifies a segment and an offset (memory location) within that segment. Segments or sections are also used in ...

  6. Page table - Wikipedia

    en.wikipedia.org/wiki/Page_table

    A page table is a data structure used by a virtual memory system in a computer to store mappings between virtual addresses and physical addresses. Virtual addresses are used by the program executed by the accessing process, while physical addresses are used by the hardware, or more specifically, by the random-access memory (RAM) subsystem.

    Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1] It can sometimes be a high-level description that ignores details of the implementation. [2] At a more detailed level, the description may include the ...

  8. x86 memory segmentation - Wikipedia

    en.wikipedia.org/wiki/X86_memory_segmentation

    If the paging unit is enabled, addresses in a segment are now virtual addresses, rather than physical addresses as they were on the 80286. That is, the segment starting address, the offset, and the final 32-bit address the segmentation unit derived by adding the two are all virtual (or logical) addresses when the paging unit is enabled.

  9. Page (computer memory) - Wikipedia

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

    A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in a page table. It is the smallest unit of data for memory management in an operating system that uses virtual memory. Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory ...
