The Internet is a large group of computers that are connected to each other, used to send information quickly between computers around the world. It has millions of smaller domestic, academic, business, and government networks, which together carry lots of different information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other documents of the World Wide Web.

[change] History
The Internet was created in the United States in 1969 by the "United States Department of Defense Advanced Research Projects Agency" (known as ARPA). The World Wide Web was created at CERN in Switzerland in the 1990s by a British (UK) man named Tim Berners-Lee.
Today, people can pay a fee to access the Internet from Internet Service Providers. Some services on the Internet cost nothing to use. Sometimes the people who offer these free services use advertising to make money from them. The alternative name, "Net" came from "inter(net)".
[change] Services on the Internet
The Internet is used for many things, such as electronic mail (e-mail), online chat, and the World Wide Web.
The most used service on the Internet is the World Wide Web (which is also called the "Web"). The Web contains websites, blogs, and also wikis - including Wikipedia. Webpages on the Web can be seen and read by anyone (unless the page needs a password, or it is blocked).
The second major use of the Internet is to send and receive e-mail. E-mail is private and goes from one user to another. Instant messaging (such as AIM or ICQ) is similar to email, but allows two or more people to chat to each other much faster.
Some governments consider the Internet to be a bad thing, and block all or part of it. For example, the Chinese government thinks that Wikipedia is bad, so often no one in China can read it or add to it.[1] Some parents block parts of the Internet they think are bad for children to see. Well-known examples of the whole Internet being blocked are in North Korea[2] and Myanmar.
[change] Dangers on the Internet
The Internet can also be a dangerous place. Information people put on the Internet is not always checked.
- Some websites may trick people into downloading viruses that can harm a computer or spyware that spies on its users (looks at what they are doing and tells someone else). E-mails can also have harmful files with them as "attachments".[3]
- In Internet Chatrooms, people might be preying on others or trying to stalk them.
