  2. Trim (computing) - Wikipedia

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

    TRIM is an ATA command (Advanced Technology Attachment Command) that allows an OS to inform SSD about the blocks of data no longer in use. The SSD then deletes such blocks of data to make a way for newer blocks of data. TRIM is basically used for enhancing the performance and life span of the SSD.

  3. CPU cache - Wikipedia

    en.wikipedia.org/wiki/CPU_cache

    CPU cache. A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.

  4. Cache (computing) - Wikipedia

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

    Cache (computing) In computing, a cache (/ kæʃ / ⓘ 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. A cache hit occurs when the requested data can be found in ...

  5. Disk buffer - Wikipedia

    en.wikipedia.org/wiki/Disk_buffer

    The disk buffer is controlled by the microcontroller in the hard disk drive, and the page cache is controlled by the computer to which that disk is attached. The disk buffer is usually quite small, ranging between 8 MB to 4 GB, and the page cache is generally all unused main memory. While data in the page cache is reused multiple times, the ...

    To clear the cache: Go to the "Tools" menu (the three horizontal ellipsis on the upper right of the browser) and click on "History" (Shortcut: Ctrl + H). Click on "Clear browsing data…". (Shortcut: Ctrl + ⇧ Shift + Del). Select the types of data you want to clear, and include "Cached images and files" option.

    Flush one cache line to memory. In a system with multiple cache hierarchy levels and/or multiple processors each with their own caches, the line is flushed from all of them. 3 (SSE2), Geode LX: MONITOR [k] Monitor a memory location for memory writes. MONITOR [l] MONITOR EAX,ECX,EDX: NP 0F 01 C8: Start monitoring a memory location for memory writes.

  8. Cache prefetching - Wikipedia

    en.wikipedia.org/wiki/Cache_prefetching

    Cache prefetching. Cache prefetching is a technique used by computer processors to boost execution performance by fetching instructions or data from their original storage in slower memory to a faster local memory before it is actually needed (hence the term 'prefetch'). [1][2] Most modern computer processors have fast and local cache memory in ...

  9. Slab allocation - Wikipedia

    en.wikipedia.org/wiki/Slab_allocation

    Cache: cache represents a small amount of very fast memory. A cache is a storage for a specific type of object, such as semaphores, process descriptors, file objects, etc. Slab: slab represents a contiguous piece of memory, usually made of several virtually contiguous pages. The slab is the actual container of data associated with objects of ...
