Believe it or not, modern computers have cookies on them. Not the chocolate chip kind you may be thinking of.
Cookies are files left on your computer by websites to remember specific information. When a user goes back to a site in the future, the cookie (special file) can be opened to retrieve the saved information. This is one way sites can allow you to have a customized startup page on their site.
Because of cookies, websites can have thousands or even millions of users and still remember each user’s settings and choices because they are saved on the user’s computer rather than on the web server.
The European Union just recently enacted a law that requires websites to request permission before they can save cookies on users’ computers. This law goes into effect this month.
