What is a cookie?
A cookie is a small file of data that an Internet server places on the hard drive of a user by way of the browser. This information can be passed to the server each time the browser is used, and its purpose is as a way of identifying the user without the need for a password. More elaborate cookies can be used to identify preferences (for Internet shopping, for example). Browsers contain options for restricting or eliminating cookie storage.
