internet

The Internet is a global network connecting millions of computers. More than 190 countries are linked into exchanges of data, news and opinions.

The Internet is not synonymous with World Wide Web. The Internet is a massive network of networks, a networking infrastructure. It forms a network in which any computer can communicate with any other computer as long as they are both connected to the Internet.

Unlike online services which are centrally controlled, by design, the Internet is decentralized. Each Internet computer, called a host, is independent. Operators can choose which Internet services to use and which local services to make available to the global Internet community. Remarkably, this anarchy by design works exceedingly well. There are a variety of ways to access the Internet. Most online services offer access to some Internet services. It is also possible to gain access through a commercial Internet Service Provider (ISP).

No one actually owns the Internet, and no single person or organization controls the Internet in its entirety. The Internet is more of a concept than an actual tangible entity, and it relies on a physical infrastructure that connects networks to other networks.
