Definition: Pronounced “cash,” a cache is used to store data temporarily to speed up processing.

What This Means: A large cache allows a computer to move the data needed at the moment out of larger tables and into a temporary area where calculations and other actions can be done faster. Cache capacity can affect performance of software as much or more than other factors. Browser caches and Internet caches store copies of web pages to speed up retrieval the next time the same page is requested.
