Cache

Part of the computer memory that stores information for quick retrieval. When a computer displays a web page the information is stored so that if the page is visited again information can be retrieved from within the local computer rather than being downloaded from the network. Information obtained from the internet is stored in a temporary file (cache) which has a pre determined capacity so that when it becomes full new information replaces the old. Cached files can be removed from your computer but it does not happen automatically.
