global system of connected computer networks based on IP addressing and routing protocols

The Internet is the biggest world-wide communication network of computers. The Internet has a lot of smaller domestic, academic, business, and government networks, which together carry many different kinds of information. The short form of internet is the 'Net'. The World Wide Web is one of its biggest services. It is used by countless people all over the world.

The Internet was developed in the United States by the Department of Defence Advanced Research Projects Agency (DARPA). The Internet was first connected in October 1969[1] and was called ARPANET. The World Wide Web was created at CERN in Switzerland in 1990 by a British (UK) scientist named Tim Berners-Lee.

Today, people can pay money to access the Internet from internet service providers. Some services on the Internet cost nothing to use. Sometimes people who offer these free services use advertising to make money. Censorship and freedom of speech on the Internet can be controversial.

The Internet is used for many things, such as electronic mail, online chat, file transfer and other documents of the World Wide Web.

The most used service on the Internet is the World Wide Web (which is also called the "Web" or “www”). The web contains websites, including social media, blogs, and wikis like Wikipedia. Webpages on the Internet can be seen and read by anyone (unless the page needs a password, or it is blocked).

The second biggest use of the Internet is to send and receive e-mail. E-mail is private and goes from one user to another. Instant messaging is similar to email, but allows two or more people to chat to each other faster.

Some governments think the internet is 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.[2] Another example of the internet being blocked is in North Korea.[3] Some parents and schools block parts of the Internet they think are bad for children to see.



The Internet makes communication easy. Yet, communication can be dangerous, too. People often send secret information, and sometimes other people can steal that information. They can use the Internet to spread lies, steal secrets, or give dangerously bad advice. For example, Facebook has had some problems with privacy settings.
