What is the Internet?The Internet is the world's largest computer network that you can use to exchange ideas and develop knowledge. The Internet connects over 20 million people. Users on the Internet can send e-mail to each other, download files, participate in online discussions on a variety topics and even purchase products.
The Internet is actually a "network of networks." The networks that comprise it are thousands of local-area networks--groups of computers connected by cables--that have been set up by universities, government agencies, research institutions, and corporations all over the world.
Information on the Internet can reside on any one of the thousands of computers, known
as servers, that are connected to the Internet. The Internet contains a variety of
different servers (e.g. Gopher, FTP, World Wide Web, Usenet News) that store information
in different formats. Each type of server requires a different client application to
browse the information on that particular server. These client applications, called
browsers, provides a set of client tools that allow you to view, download, and search for
information from any of the servers on the Internet.
