What is Cache?

A file on the hard drive or a section in memory in which a Web browser stores information like links, text and graphics from recently visited Web sites. It offers the advantage of much quicker loading when files are stored on disk than when they must be transferred from the web. The disadvantage is that it will sometimes show you an old version of a file from your disk when a newer one is available on the web. In such cases you can check for a newer version by using the Refresh or Reload selections in your browser. Some large Internet service providers also cache frequently visited sites and feed them to you from their own cache when you try to visit them.
