What is a Cache?

Cache. A web browser's cache is where it keeps files (images, cookies, etc.) that it has downloaded from the web while you were viewing a web page and might need to use again. A site's logo and navigation graphics may be stored in the browsers cache, for example, so that they don't have to be downloaded again and again each time you go from one page of the site to another page of the site. This happens automatically. It's a good idea to clear the cache every so oftern so that you computer doesn't get bogged down.
