Some computer systems record information about your Web visits. Here are brief descriptions of three.
Mouse Tracks
These are bits of information some sites collect about what pages you visit as you explore their Web sites.
Cookies
These are bits of information deposited by a Web site in the "cookie" file of your computer software. Cookies let a Web site keep track of information about your visit, such as which parts of the site you visited. This information can be used by the Web-site operators to determine if you are a repeat visitor and what parts of the site interest you. Cookies can also allow you to move more quickly through the Internet because your preferences and past activities are already recorded. The file where cookies are deposited is in the software you use to browse the Internet. Some browsers can be set to notify you if cookies are being activated. Most browsers will let you deactivate the file or delete cookies in it.
Registration
Web sites may ask visitors to register and provide personal details including your name, e-mail address, home address or phone number. It's a good idea to review the privacy statement of the Web site to learn how the information you provide will be used. Then you can decide whether you want to register or not.
