4. W3: The Newest Fastest Growing Communications System In this section we shall discuss: 4 A Brief Current State of the World Wide Web Report 4 Cyberspace and The World Wide Web Defined 4 WWW Protocols 4 WWW Addresses and Domain Names 4 The Structure of Information Nested in the Web 4 WWW Hypertext Terminology 4

5. The Current State of the World Wide Web 4 The Web’sTechnical Growth l HTML (Hyper Text Markup Language) l Java (write once, run anywhere) l VRML (Virtual Reality Modeling Language) l The Scope of the Web’s Social Acceptance (education, business, and individuals) l Challenges of meaningful and successful Web Page Development 5

6. Cyberspace and the World Wide Web Defined l The term cyberspace was coined by science fiction author William Gibson. We now use this term to describe a variety of computer related applications, such as, communication, interaction, information retrieval, and visualization. Cyberspace may be described as the “universe” of all on- line exchanges. For example, classes can be taught over the Internet, professors and students can read texts and Journal articles on- line, and various professionals can perform data searches to facilitate their theoretical and/or applied work. 6

7. W3 -- World Wide Web The Web may be described as a software application that functions within cyberspace and utilizes Internet hardware and inter- connectivity protocols as its vehicle of on-line communications and data transfer. The Internet serves as a major common network that connects numerous on- line services that maintain “access ramps” or gateways and other access protocols to the “Information Super Highway.” 7

8. W3 Protocols The Internet is comprised of a large number of independent, interconnected networks. By the late 1960s and early 1970s, a fairly robust on-line communications system was put into place by ARPA. Trough a set of TCP/IP data was broken into chunks, then sent over different routes and then reassembled at its point of destination. IPNG or IP version “x” is designed to solve the rapidly shrinking space of Internet host addresses. 8

9. W3 Protocols Through the utilization of several sets of rules (protocols) Web browsers can communicate with various servers on the Internet. Following is a list of some of the most popular protocols: HTTP: The Web’s built-in (native) protocol for the transmission of hypertext documents. FTP: Enables the transmission of text or binary files between computer hosts across networks Gopher: Information sharing system that utilizes menus, documents, or connections to Telnet sessions. NNTP: Protocol used for Usenet news distribution. Telnet: Protocol for remote logon to a computer host. 9

10. WWW Addresses and Domain Names WWW Addresses and Domain Names In order to facilitate its use, specific IP numeric addresses were assigned an alphanumeric host name through the Net’s DNS. Following is a selected list of high-level domain names: Domain NameType of Host.comCommercial organization.eduEducational Institution.govTypically U.S. government.milU.S. military.netNAP (e.g., pacbell.net).orgnon-profit organization Country codes may be found at: ftp://rtfm.mit.edu/pub/usenet/news.answers/mail /country-codes 11

11. Web Based Hypertext Terms l Page: Single HTML file l Home Page: HTML file that serves as the main door to a web site. l Hotlinks: Links to related pages or additional information. l Web: In a general sense represents all Home & Web pages that are accessible through a Web browser interface. l web site: Typically a collection of pages under one home page. l URL: Uniform resource locators are strings of characters that define a specific Home or any of its satellite pages. 11
