  2. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    Windows can be configured to use free space on any available drives for page files. It is required, however, for the boot partition (i.e., the drive containing the Windows directory) to have a page file on it if the system is configured to write either kernel or full memory dumps after a Blue Screen of Death .

  3. Resident set size - Wikipedia

    en.wikipedia.org/wiki/Resident_set_size

    In computing, resident set size (RSS) is the portion of memory (measured in kilobytes) occupied by a process that is held in main memory ().The rest of the occupied memory exists in the swap space or file system, either because some parts of the occupied memory were paged out, or because some parts of the executable were never loaded.

  4. zram - Wikipedia

    en.wikipedia.org/wiki/Zram

    Using compressed swap space with zram or zswap also offers advantages for low-end hardware devices such as embedded devices and netbooks. Such devices usually use flash-based storage, which has limited lifespan due to write amplification, and may also use it to provide swap space. Using zram or zswap reduces the swap usage, which effectively ...

  5. top (software) - Wikipedia

    en.wikipedia.org/wiki/Top_(software)

    %Cpu(s) counts the percentage of CPU usage, broken down into categories. MiB Mem: Memory usage in units of mebibyte. The buff/cache is for memory used by buffers and cache. MiB Swap: Swap space usage in units of mebibyte. If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the swap space.

  6. Thrashing (computer science) - Wikipedia

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

    The first version of swap-token is implemented in Linux. The second version is called preempt swap-token. In this updated swap-token implementation, a priority counter is set for each process to track the number of swap-out pages. The token is always given to the process with a high priority, which has a high number of swap-out pages.

  7. Commit charge - Wikipedia

    en.wikipedia.org/wiki/Commit_charge

    The Windows Task Manager utility for Windows XP and Server 2003, in its Performance tab, shows three counters related to commit charge: . Total is the amount of pagefile-backed virtual address space in use, i.e., the current commit charge.

  8. Memory management - Wikipedia

    en.wikipedia.org/wiki/Memory_management

    Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.

  9. 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".
