Cookies are messages that web servers pass to your web browser when you visit Internet sites. Your browser stores each message in a small file. When you request another page from the server your browser sends the cookie back to the server. These files typically contain information about your visit to the web page as well as any information you've volunteered such as your name and interests. Cookies are most commonly used to track web site activity. When you visit some sites the server gives you a cookie that acts as your identification card. Upon each return visit to that site your browser passes that cookie back to the server. In this way a web server can gather information about which web pages are used the most and which pages are gathering the most repeat hits. Only the web site that creates the cookie can read it. Additionally web servers can only use information that you provide or choices that you make while visiting the web site as content in cookies. Accepting a cookie does not give a server access to your computer or any of your personal information. Servers can only read cookies that they have set so other servers do not have access to your information. Also it is not possible to execute code from a cookie and not possible to use a cookie to deliver a virus.
