The connection between the computers is some kind of electrical connection, whether it be copper wire, fiber optic or radio waves. You might not have though about it before, but networks are everywhere. When you watch TV, you are getting data over a network. When you are talking on the telephone, you are using a network. When you are on the internet, you are using a network.
