  2. Page cache - Wikipedia

    en.wikipedia.org/wiki/Page_cache

    Pages in the page cache modified after being brought in are called dirty pages. [5] Since non-dirty pages in the page cache have identical copies in secondary storage (e.g. hard disk drive or solid-state drive), discarding and reusing their space is much quicker than paging out application memory, and is often preferred over flushing the dirty pages into secondary storage and reusing their space.

  3. 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.

  4. Cache (computing) - Wikipedia

    en.wikipedia.org/wiki/Cache_(computing)

    Diagram of a CPU memory cache operation. In computing, a cache (/ k æ ʃ / ⓘ KASH) [1] is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.

  5. Clear cache on a web browser - AOL Help

    help.aol.com/articles/clear-cookies-cache...

    A browser's cache stores temporary website files which allows the site to load faster in future sessions. This data will be recreated every time you visit the webpage, though at times it can become corrupted. Clearing the cache deletes these files and fixes problems like outdated pages, websites freezing, and pages not loading or being ...

  6. Dirty bit - Wikipedia

    en.wikipedia.org/wiki/Dirty_bit

    The dirty bit for a page is set by the hardware whenever any word or byte in the page is written into, indicating that the page has been modified. When a page is selected for replacement, the modify bit is examined. If the bit is set, the page has been modified since it was read in from the disk. In this case, the page must be written to the disk.

  7. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    Those machines, and subsequent machines supporting memory paging, use either a set of page address registers or in-memory page tables [d] to allow the processor to operate on arbitrary pages anywhere in RAM as a seemingly contiguous logical address space. These pages became the units exchanged between disk and RAM.

  9. Translation lookaside buffer - Wikipedia

    en.wikipedia.org/wiki/Translation_lookaside_buffer

    Hence, the TLB is used to reduce the time taken to access the memory locations in the page-table method. The TLB is a cache of the page table, representing only a subset of the page-table contents. Referencing the physical memory addresses, a TLB may reside between the CPU and the CPU cache, between the CPU cache and primary storage memory, or ...
