  2. Virtual memory - Wikipedia

    en.wikipedia.org/wiki/Virtual_memory

    Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".

  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 ...

  4. Thrashing (computer science) - Wikipedia

    en.wikipedia.org/wiki/Thrashing_(computer_science)

    Thrashing (computer science) In computer science, thrashing occurs in a system with virtual memory when a computer's real storage resources are overcommitted, leading to a constant state of paging and page faults, slowing most application -level processing. [1] This causes the performance of the computer to degrade or even collapse.

  5. x86 virtualization - Wikipedia

    en.wikipedia.org/wiki/X86_virtualization

    x86 virtualization. x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance.

    It was a virtual memory compression utility for Windows 3.1, Windows For Workgroups and Windows 95. MagnaRAM is included with QEMM 97. MagnaRAM was also released as a separate utility. [2] MagnaRAM worked by replacing a portion of Windows' virtual memory system. MagnaRAM would insert itself in the string of Windows Programs that determined what ...

  8. Memory management unit - Wikipedia

    en.wikipedia.org/wiki/Memory_management_unit

    A memory management unit (MMU), sometimes called paged memory management unit (PMMU), [1] is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory. In modern systems, programs generally have addresses that access the ...

  9. Commit charge - Wikipedia

    en.wikipedia.org/wiki/Commit_charge

    Commit charge. In computing, commit charge is a term used in Microsoft Windows operating systems to describe the total amount of virtual memory of all processes that must be backed by either physical memory or the page file. [1] Through the process of paging, the contents of this virtual memory may move between physical memory and the page file ...
