Think about it like a storage for files that the computer may need for 'quick' reference. In a browser, a cache of images may be kept so that if the person revisits the site, the browser can immediately point to the cached picture instead of re-downloading it all over again.

A cache is used to speed up data transfer and may be either temporary or permanent. Memory and disk caches are in every computer to speed up instruction execution and data retrieval and updating. These temporary caches serve as staging areas, and their contents are constantly changing.

Browser caches and Internet caches store copies of Web pages retrieved by the user for some period of time in order to speed up retrieval the next time the same page is requested.

A memory cache, or "CPU cache," is a memory bank that bridges main memory and the CPU. It is faster than main memory and allows instructions to be executed and data to be read and written at higher speed. Instructions and data are transferred from main memory to the cache in fixed blocks, known as cache "lines," using some kind of look-ahead algorithm.
