  1. Web FundamentalsTraining Series • All About the Web

  2. What We’ll Be Covering… • What the Web Is (and Isn’t) • The World Wide Web: A Brief History • How the Web Works • Internet Components • Internet Transmission • Transmission Optimization • How the Web Enhances the Internet • What’s to Come

  3. What the Web Is (and Isn’t) • The World Wide Web IS… • A global information medium which users can both read and write to via computers • The World Wide Web IS NOT… • The Internet • The Web is a service on the Internet, like e-mail is • The Internet, under different names and forms, has been around significantly longer than the WWW (since the early 1970’s)

  4. The World Wide Web: A Brief History • Originated with and developed by Tim Berners-Lee in 1980’s • Originally conceived to link electronic documents together via hypertext • Aug. 1991: World Wide Web publicly released • Typically used by university based science departments • Aug. 1994: Commercialization of the Web begins • First business on Web was Pizza Hut (1994) • By 1998, e-business was fairly commonplace • Sept. 1994: World Wide Web Consortium (W3C) founded at MIT • Now the governing body of the World Wide Web • Develops standards for web technology and practices • Kept WWW code royalty free and publicly accessible

  5. How the Web Works • The technology behind the concept is quite complex • Electronics Technology • Computing Devices • Cell Phones • Network (Internet) Technology • Wired • Wireless • Software Technology • Databases • Games • The overall concept is simple • View files via a browser • Click on hyperlinks to move to the area of interest • View and/or download the information

  6. Internet Components • Many different components are required for the Internet to work and, in turn, provide users with the Web service • Additionally, several different transmission methods are now available, adding to the complexity • Dial-Up / DSL • Broadband • Wireless • Satellite • Wi-Fi / WiMAX • But, it all boils down to requesting and receiving information

  7. REQUEST RESPONSE The Client / Server Relationship • Client: some form of user, human or automated, who makes a request for some type of electronic information or resource. • Server: stores electronic information in the form of files and “serves” a response to requesting clients

  8. Internet Transmission • Requires a complicated combination of hardware, software, and industry protocols • In brief, each Internet transaction that occurs such as: a hyperlink that is clicked on, e-mail, Instant Message, or a file that is downloaded, goes through the following process • Request / message is broken down into small, electronic packets • Packets are numbered by the requestor’s computer • Packets are routed through the Internet to the appropriate address • Receiver’s computer acknowledges the receipt of each packet • Packets are reassembled by receiver’s computer • Receiver responds, as necessary • Process repeats

  9. Transmission Optimization • Literally, countless trillions of packets are flying through transmission paths all over the world at any given second • The bigger the file, the slower the transmission • Some multimedia files can be very resource dependent. These files include the following: • Still Images • Audio • Animations & Video • In terms of web publications, it’s always a best practice to use the least amount of resources possible. In doing so, you not only better serve your audience, but also make less demands on the system as a whole.

  10. Mosaic (1993) Console View Firefox (2008) How the Web Enhances the Internet • Prior to the Web and the development of Mosaic, the first web browser, all Internet transmissions were console based and text only. No pictures. No sound • This has definitely changed • Web pages created to today’s expectations and standards have benefits, but also drawbacks +Visually and audibly appealing + User friendly • High demand on resources • Many “power” users don’t understand supporting system issues

  11. What’s to Come • Multimedia is a collection of different media forms which includes various combinations of the following: • Text • Still Images • Audio • Video / Animation • The tutorial series that follows this presentation is not meant to be comprehensive, but rather a starting point to help a user make the most out of available resources while creating a functional, appealing web page.

  12. Conclusion • This completes the Web Fundamentals tutorial.
