1797, "hiding place," from French Canadian trappers' slang, "hiding place for stores" (1660s), a back-formation from French cacher "to hide, conceal" (13c., Old French cachier), from Vulgar Latin *coacticare "store up, collect, compress," frequentative of Latin coactare "constrain," from coactus, past participle of cogere "to collect" (see cogent). Sense extended by 1830s to "anything stored in a hiding place."

n. 1 A store of things that may be required in the future, which can be retrieved rapidly, protected or hidden in some way. 2 (context computing English) A fast temporary storage where recently or frequently used information is stored to avoid having to reload it from a slower storage medium. 3 (context geocaching English) A container containing treasure in a global treasure-hunt game. vb. 1 To place in a cache. 2 (context Marijuana smoking English) For the herb in a bowl to be entirely burnt to ashes and therefore having become empty, gone, or useless for further smoking

Cache or caching may refer to:

• Caching or hoarding (animal behavior), a food storing behavior of animals
• A cache or hoard, a collection of artifacts
• Treasure trove, a valuable cache which has been lost, or left unclaimed by the owner, or a place where items are stored
• Geocaching, an outdoor treasure-hunting game which involves looking for containers of varying sizes called geocaches or caches
• Bear cache, a bear-safe storage facility

In computing, a cache , is a hardware or software component that stores data so future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation, or the duplicate of data stored elsewhere. A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot. Cache hits are served by reading data from the cache, which is faster than recomputing a result or reading from a slower data store; thus, the more requests can be served from the cache, the faster the system performs.

To be cost-effective and to enable efficient use of data, caches are relatively small. Nevertheless, caches have proven themselves in many areas of computing because access patterns in typical computer applications exhibit the locality of reference. Moreover, access patterns exhibit temporal locality if data is requested again that has been recently requested already, while spatial locality refers to requests for data physically stored close to data that has been already requested.

Caché , titled Hidden in the UK and Ireland, is a 2005 French psychological thriller written and directed by Michael Haneke. Starring Daniel Auteuil as Georges and Juliette Binoche as his wife Anne, the film follows an upper-class French couple who are terrorized by anonymous tapes that appear on their front porch and hint at childhood memories of the husband.

Caché opened to acclaim from film critics, who lauded Binoche's acting and Haneke's direction. The ambiguities of its plot continue to attract considerable discussion among scholars; many have commented on the film's themes of "bourgeois guilt" and collective memory, often drawing parallels between its narrative and the French government's decades-long denial of the 1961 Seine River massacre. Caché is today regarded as one of the greatest films of the 2000s.
