Cache

Caching (pronounced CASH-ing) is a technique computers use to save memory by storing frequently accessed files.

Web browsers have caches that keep recently downloaded web pages handy. Browser caches are typically kept on your local drive, and you can usually adjust the amount of memory or disk space allotted for the cache. The benefit of web caches is that you can access a cached page much more quickly than if you downloaded it from a distant server.
