Windows NT Once a small and simple collection of computers run by the Defence Department, is now a massive world wide network of computers, what we call the 'Internet'. The word "Internet" literally means "network of networks." In itself, the Internet is composed of thousands of smaller local networks scattered throughout the globe. It connects roughly 15 million users in more than 50 countries a day. The World Wide Web (WWW) is mostly used on the Internet. The Web refers to a body of information, while the Internet refers to the physical side of the global network containing a large amount of cables and computers.
