Advantages and Disadvantages of the Internet
Ten years ago, the Internet was practically unheard of by most people. Today, the Internet is one of the most powerful tools throughout the world. The Internet is a collection of various services and resources. According to Russ Brock, a director and consultant at the Center for Innovation and Inquiry, the Internet’s main components are E-mail and the World Wide Web. “There’s a lot more to the Internet than E-mail, search engines, celerity web sites, up-to-the-second sports scores, and chat rooms full of risqué discussions. The Net also ranks as one of today’s best business tools - if it’s used adroitly”. Almost all households contain the Internet; however, before people connect to the Internet, they need to be aware of its disadvantages and advantages.
Another major disadvantage of the Internet is privacy. Electronic messages sent over the Internet can be easily snooped and tracked, revealing who is talking to whom and what they are talking about. As people surf the Internet, they are constantly giving information to web sites . People should become aware that the collection, selling, or sharing of the information they provide online increases the chances that their information will fall into the wrong hands. Consequently, they will become a victim of identity theft, one of the worst privacy violations with potentially devastating financial consequences . When giving personal information on the Internet, people should make sure the Web site is protected with a recognizable security symbol. On the other hand, this does not mean they are fully protected because anyone may obtain a user’s information . In other words, “the most common Internet crimes are frauds and con games”
