Privacy
You may be exposing personal information online. Most Web browsers provide your name and e-mail address to Web sites you visit. Many users keep the name and e-mail fields in their browser's preferences blank.

Many people use a false identity when surfing the Internet. This includes using fake names and anonymous e-mail accounts for general online shopping or exploring, and using a real e-mail account only for personal communications with friends and family. There are many free e-mail services like Hotmail and Yahoo! Mail, so having a few extra accounts is not costly.

Security
Identity theft is when a criminal takes your personal information (name, address, social security number, credit card number) and uses it to charge items to your name. When you must provide personal information online, make sure you are using secure Web sites that you know and trust, provide as little information as possible, and delete or shred all documents. Always ask your parents or an adult you trust if you are about to provide personal information online.

Never respond to requests for personal information from unknown sources. If in doubt, call the institution that is asking for information. In addition to choose encrypted, or safe, Web sites, it is important to routinely review credit card and bank statements and to report identity theft to the proper authorities.

(Note: Use passwords at your computer login and for sensitive files or programs to provide another layer of security against intruders.)

Safety
Physical safety is key when using computers and technology. In addition to ergonomics (the study of how equipment design affects the user) and computer setup, it is important to explore various tools and hardware that can help improve computer use.

Specialized keyboards and wrist pads help reduce problems that result from awkward or heavy typing, such as Carpal Tunnel Syndrome-a painful wrist and hand condition. Raised foam and silicone wrist pads can help correct hand position while typing, and special braces can help support aching arms.

Monitor glare can strain the eye. If you find yourself experiencing unusual discomfort when working on a computer, consider a glare filter to reduce harmful light, and remember to look away from the screen and rest your eyes frequently.
