Internet cookies are small strings of text data created by a web server used to communicate with a web browser running on a computer. Cookies allow websites to "remember" a computer so that data can be transmitted more quickly if the user gets on the site that transmitted the cookie again. They contain only text data that is not program code and thus are in themselves harmless to a computer.
