What Is the Internet?

The Internet is made up of millions of computers linked together around the world in such a way that information can be exchanged between any computer at any time. These computers can be in homes, schools, universities, government departments, or businesses small and large.

The Internet is often described as 'a network of networks' because all the smaller networks of organizations are linked together into the one giant network called the Internet

Today, most people take the Internet for granted, much like they do a telephone line. Instead of marveling at the Internet’s internal gearing, they’ve grown accustomed to this new land called cyberspace and its healthy stock of attractions:

Library: The Internet is stuffed with educational material: classic books, hourly news updates, foreign language dictionaries, specialized encyclopedias, and more.

Store: Although the Internet seemed like a novelty ten years ago, today the Internet revolves around making money. You can purchase nearly anything available in online stores .

Communicator: Many people treat the Internet as a private postal service for sending messages to friends around the world.

Time waster: When sitting in a waiting room, everybody naturally reaches for the magazine table. The Internet, too, offers zillions of ways to waste time.

Entertainment: The Internet brings not only a movie’s show times into your home, but also its trailers, cast lists, reviews, and celebrity gossip. If you’re tired of movies, browse for online games, research exotic travel destinations, or look up sporting statistics.
