  2. 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 ...

  3. 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".

  4. Thrashing (computer science) - Wikipedia

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

    In effect, physical main memory becomes a cache for virtual memory, which is in general stored on disk in memory pages. Programs are allocated a certain number of pages as needed by the operating system. Active memory pages exist in both RAM and on disk. Inactive pages are removed from the cache and written to disk when the main memory becomes ...

  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 Clearing the cache deletes these files and fixes problems like outdated pages, websites freezing, and pages not loading or being ...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. Virtual memory compression - Wikipedia

    en.wikipedia.org/wiki/Virtual_memory_compression

    By reducing the I/O activity caused by paging requests, virtual memory compression can produce overall performance improvements. The degree of performance improvement depends on a variety of factors, including the availability of any compression co-processors, spare bandwidth on the CPU, speed of the I/O channel, speed of the physical memory, and the compressibility of the physical memory ...

  7. Translation lookaside buffer - Wikipedia

    en.wikipedia.org/wiki/Translation_lookaside_buffer

    A translation lookaside buffer (TLB) is a memory cache that stores the recent translations of virtual memory to physical memory. It is used to reduce the time taken to access a user memory location. [1] It can be called an address-translation cache. It is a part of the chip's memory-management unit (MMU).

  8. Memory virtualization - Wikipedia

    en.wikipedia.org/wiki/Memory_virtualization

    While these technologies dynamically manage memory within individual computers, memory virtualization manages the aggregated memory of multiple networked computers as a single memory pool. In tandem with memory management innovations, a number of virtualization techniques have arisen to make the best use of available hardware resources.
