Session 1
The Internet and the World Wide Web
The Internet , in the simplest of terms, is a worldwide collection of networks. A network
is composed of two or more computers that are linked together and that share and
exchange information. The Internet is the world’s largest network, made up of computers
located all over the world. The computers and networks that make up the Internet are
connected by fiber-optic cables, satellites, phone lines, and other forms of electronic
communication media, as shown in Figure 1.

The Internet and the services it provides allow people all over the world to communi-
cate and share information quickly and easily. The World Wide Web (WWW) , or simply
the Web , is a service the Internet offers that enables individuals and businesses to test and
market products and services to a global audience. The Web is a system of electronic doc-
uments, called Web pages , that are linked together by hyperlinks (or just links ), which are
words, phrases, or graphics in a Web page that target another place in the document or
another document altogether. When a user clicks a hyperlink, the information at the target
location is displayed, as shown in Figure 2.
