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.
Cache (computing), a technique used in computer storage for easier data access Cache (biology) or hoarding, a food storing behavior of animals Cache (archaeology) , artifacts purposely buried in the ground
In computer storage, a disk buffer (often ambiguously called a disk cache or a cache buffer) is the embedded memory in a hard disk drive (HDD) or solid-state drive (SSD) acting as a buffer between the rest of the computer and the physical hard disk platter or flash memory that is used for storage.

Event: An event cache is a gathering of local geocachers or geocaching organizations. The event cache page specifies a time for the event and provides coordinates to its location. [33] Event caches have to be longer than 30 minutes, and can publish no less than 14 days away from the planned event date. Event caches typically last from 1 to 2 hours.
A forward cache is a cache outside the web server's network, e.g. in the client's web browser, in an ISP, or within a corporate network. [3] A network-aware forward cache only caches heavily accessed items. [4] A proxy server sitting between the client and web server can evaluate HTTP headers and choose whether to store web content.
In computing, memoization or memoisation is an optimization technique used primarily to speed up computer programs by storing the results of expensive function calls to pure functions and returning the cached result when the same inputs occur again.

Cache prefetching can be accomplished either by hardware or by software. [3]Hardware based prefetching is typically accomplished by having a dedicated hardware mechanism in the processor that watches the stream of instructions or data being requested by the executing program, recognizes the next few elements that the program might need based on this stream and prefetches into the processor's ...
