  2. 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 ...

  3. Page table - Wikipedia

    en.wikipedia.org/wiki/Page_table

    Physical memory can contain pages belonging to many processes. Pages can be held on disk if seldom used, or if physical memory is full. In the diagram above, some pages are not in physical memory. 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.

  4. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    A process can store data in memory-mapped files on memory-backed file systems, such as the tmpfs file system or file systems on a RAM drive, and map files into and out of the address space as needed. A set of processes may still depend upon the enhanced security features page-based isolation may bring to a multitasking environment.

  5. 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.

  6. Translation lookaside buffer - Wikipedia

    en.wikipedia.org/wiki/Translation_lookaside_buffer

    This method uses two memory accesses (one for the page-table entry, one for the byte) to access a byte. First, the page table is looked up for the frame number. Second, the frame number with the page offset gives the actual address. Thus, any straightforward virtual memory scheme would have the effect of doubling the memory access time.

  7. 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.

  9. Page fault - Wikipedia

    en.wikipedia.org/wiki/Page_fault

    In computing, a page fault is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process's virtual address space. Furthermore, the actual page contents may need to be loaded from a back-up, e.g. a disk.
