The Internet is a collection of computer networks talking to each other using a process called packet switching. All communication between computers on the Internet happens by cutting things up into small packets and sending them through a system of electronic routing stations to their destination.

The Internet is a lot like the postal service in many ways. All post offices are connected by roads and mail trucks move between them. If you want to send a letter to someone else, you have to provide three things: The receiver's address, your address so it can come back to you if it does not go all the way to the receiver's house, and a message. You give the letter to the mailman and he takes care of it. The letter will be taken to a post office where it will be sorted and put on a truck that will take it to its destination. It would be wasteful if your letter was the only one in the truck. Instead it shares the truck with hundreds of other letters and packages. This is basically how the Internet works.

The only major difference, between the mail and the internet, is that in the internet information is sent in small packages. This is the same as if you had a long letter to write, but you could only use postcards. Once sent they would all arrive at their destination in a random order. The reciver would put them back together so he could understand the message. This is what happens on the internet.
