There's one major distinction between an intranet and the Internet:The Internet is an open, public space,while an intranet is designed to be a private space.

Well internet is the global computer network in which there are many computers connected and they can contact with each other. For example: when you go to a web page you visit a directory in another computer connected on the internet which is called a server. Intranet is mostly said about the connection between not as much computers as on the net and it is called LAN (Local Area Network). There is another internet now called internet2 but it is between big companies and the speed there is like 100 gigabits per second! wow :)
