Question

What is the definition of "cache," and in what circumstances would it be appropriate to use it?

Answer 1

"Cache" comes from the French "cacher", meaning "to hide"; ergo it became the name of a secret or inaccessible place, a place meant to hide things and keep them away until future use; and by extension it became a set of items (of the same kind at first) stored in a hidden place; it was also appropriated to use the term to name the storage of weapons and antiques.

It is appropriate to use the term in computer jargon referring to a place in the memory where data is held for future requests, or a copy of data that is saved somewhere else, saying "store data in cache".

It is appropriate to use "Cache" as a noun and as a verb as well,

i.e. "cached data".

Answer 2

The word "cache" means a collection of hidden items. A cache is like a hidden stockpile, or hidden supply. One might have a cache of weapons or even of treasure. It would be appropriate to use this term to describe a pile of items that someone would want to hide for later. For example, a pirate might have a cache of gold. A thief might have a cache of stolen property. A criminal might have a cache of weapons.
