A message from a web server computer, sent to and stored by your browser on your computer. The browser stores the message in a file called cookie.txt.

A cache temporarily stores web pages you have visited in your computer. When you use GO or BACK to revisit a document, the browser first checks to see if it is in cache and retrieves it from there because it is much faster than retrieving it from the server. When viewing information such as market reports make sure you hit refresh to ensure the latest copy is shown to you and not the one from your cache.
