The Internet

The Internet is simply the world's biggest computer network. It connects millions of hosts (computers, servers, devices, and so on) to each other so that they can communicate and interact.

The Internet is not a physical entity, nor is it any particular host or set of hosts. You could never point to a machine and identify it as the Internet, nor could you ever turn the Internet on or off. The Internet is a living entity, and one that is evolving and changing all the time.
