  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)

    This would be time-consuming. It would be much faster if the reader had a listing of how many words are on each page. From this listing they could determine which page the 5,000th word appears on, and how many words to count on that page. This listing of the words per page of the book is analogous to a page table of a computer file system. [5]

  4. Cache coloring - Wikipedia

    en.wikipedia.org/wiki/Cache_coloring

    Illustration of cache coloring. Left is virtual memory spaces, center is the physical memory space, and right is the CPU cache.. A physically indexed CPU cache is designed such that addresses in adjacent physical memory blocks take different positions ("cache lines") in the cache, but this is not the case when it comes to virtual memory; when virtually adjacent but not physically adjacent ...

  5. Computer memory - Wikipedia

    en.wikipedia.org/wiki/Computer_memory

    Volatile memory is computer memory that requires power to maintain the stored information. Most modern semiconductor volatile memory is either static RAM (SRAM) or dynamic RAM (DRAM). [a] DRAM dominates for desktop system memory. SRAM is used for CPU cache. SRAM is also found in small embedded systems requiring little memory.

  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. 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 ...

  8. 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 ...
