26. 26 The Internet and World Wide Web The Internet is a large system of interconnected computer networks that spans the globe. The Internet supports e-mail, online newspapers and publications, discussion group, game, and free software. The World Wide Web includes an easy-to-use standard interface for Internet resources accesses.

27. 27 Origins of the Internet In the early 1960s, the U.S. Department of Defense started research on networking computers. Its researchers developed a multiple channels network. In 1969, the Defense Department used this network model to connect four mainframe computers at different locations.

28. 28 New Uses for the Internet In 1972, a researcher wrote a program that could send and receive messages over the network. E-mail was born and became widely used. The network software include: –File Transfer Protocol (FTP) –User’s News Network (Usenet)

29. 29 Commercial Use of the Internet Companies used PC to construct their networks in 1980s. National Science Foundation (NSF) funded the network services in 1980s. In 1989, NSF permitted two commercial e- mail services. As the 1990s began, the Internet started to serve the global resource accesses.

30. 30 Growth of the Internet In 1991, the NSF further eased its restriction on Internet commercial activity. The privatization of the Internet was substantially completed in 1995. The new structure of the Internet was based on four network access points (NAPs). Internet service providers (ISPs) sell Internet access rights directly to customers. Click to see Figure 1-6

32. 32 Development of Hypertext In the 1960s, Ted Nelson described his page-linking system hypertext. In 1987, Nelson published a book about a global system for online hypertext publishing and commerce. In 1991, Berners-Lee of CERN developed the code for a hypertext server program and made it available on the Internet.

33. 33 HTML A hypertext server is a computer that stores files written in the hypertext markup language (HTML). HTML is a language that includes a set of codes (or tags) attached to text. A hypertext link points to another location in the same or another HTML document.

34. 34 Web Browser and Markup Languages A web browser is a software interface that lets users browse HTML documents. HTML is based on Standard Generalized Markup Language (SGML). eXtensible Markup Language (XML) allows users to define new meanings for its commands in web page. Click to see Figure 1-7
