How to use cache

Cache is used both for physical hidden stores (often of supplies or weapons discovered by authorities) and for computing contexts where data is stored for rapid retrieval. In everyday speech, it is less common than 'store' or 'stash', but appears frequently in technical and military contexts. The computing sense has become increasingly familiar to general users.

Common phrases

cache of weapons
cache memory

A common mistake

Learners sometimes confuse cache with 'cash' (money) or fail to recognize that the computing sense does not require human intention to hide—the system handles caching automatically.
