governing body is in control of it. The Internet backbone, through which Internet
traffic flows, is owned by private companies.
      All computes on the Internet communicate with one another using the
Transmission Control Protocol/Internet Protocol suite, abbreviated to TCP/IP.
Computers on the Internet use client/server architecture. This means that the re-
mote server machine provides file and services to the user’s local client ma-
chine. Software can be installed on a client computer to take the latest access
technology. An Internet user has access to a wide variety of services: electronic
mail, file transfer, vast information resources, interest group membership, inter-
active collaboration, multimedia displays, real-time broadcasting, breaking
news, shopping opportunities, and much more.
      The Internet consists primarily of a variety of access protocols. Many of
these protocols feature programs that allow users to search for and retrieve mate-
rial made available by the protocol.

                     Components of the Internet World Wide Web

      The World Wide Web (abbreviated as the Web or WWW) is a system of
Internet servers that supports hypertext to access several Internet protocols on a
single interface. Almost every protocol type available on the Internet is accessi-
ble on the Web. This includes e-mail, FTP, Telnet, and Usenet News. In addition
to these, the World Wide Web has its own protocol: Hypertext Transfer Proto-
col, or HTTP. The operation of the Web relies primarily on hypertext as its
means of information retrieval. Hypertext is a document containing words that
are called links selectable by the user. A single hypertext document can contain
links to many documents. In the context of the Web, words or graphics may
serve as links to other documents, images, video, and sound. Links may or may
not follow a logical path, as each connection is programmed by the creator of
the source document. Overall, the Web contains a complex virtual web of con-
nections among a vast number of documents, graphics, sounds.
