Understanding the World Wide Web

The World Wide Web was developed in 1989 by Tim Berners-Lee of the European Particle Physics Lab (CERN) in Switzerland. The initial purpose of the Web was to use networked hypertext to facilitate communication among its members, who were located in several countries. Word was soon spread beyond CERN, and a rapid growth in the number of both developers and users ensued. In addition to hypertext, the Web began to incorporate graphics, video, and sound. In recent years, the use of the Web has now reached global proportions. Almost every protocol type available on the Internet is accessible on the Web. Internet protocols are sets of rules that allow for intermachine communication on the Internet. The following major protocols are accessible on the Web:

E-mail (Simple Mail Transport Protocol or SMTP) distributes electronic messages and files to one or more electronic mailboxes.

Telnet (Telnet Protocol) facilitates login to the computer host to execute commands.

FTP (File Transfer Protocol) transfers text or binary files between an FTP server and client.

Usenet (Network News Transfer Protocol or NNTP) distributes Usenet news articles derived from topical discussions on newsgroups.

HTTP (Hyper Text Transfer Protocol) transmits hypertext over networks. This is the protocol of the WWW.

Many other protocols are available on the Web. To name just one example, the Voice over Internet Protocol (VOIP) allows users to place a telephone call over the Web.

The World Wide Web provides a single interface for accessing all these protocols. This creates a convenient environment. It is no longer necessary to be conversant in these protocols within separate, command-level environments. The web gathers together these protocols into a single system. Because of this feature, and because of the web’s ability to work with multimedia and advanced programming languages, the World Wide Web is the fastest-growing component of the Internet.

The Experience of the Web

Today’s World Wide Web presents an ever-diversified experience of multimedia, programming language, and real-time communication.  It is a challenge to keep up with the rapid pace of developments.

Multimedia. The web has become a broadcast medium. It is possible to listen to audio and video over the web, both pre-recorded and live. For example, you can visit the sited of various news organizations and view the same video shown on the nightly television news. Several plugins are available for viewing these videos.  For example, Apple’s Quick Time Player downloads files with the mov extension and displays these as “movies” in a small window on your computer screen. Quick Time files can be quite large, as it may take patience to wait for the entire movie to download into your computer before you can view it.

The problem of slow download times has been answered by a revolutionary development in multimedia capability: streaming media. In this case, audio or video files are played as they are downloading, or streaming, into your computer. Only a small wait, called buffering, is necessary before the file begins to play. The RealPlayer plug-in plays streaming audio and video files. Extensive files such as interviews, speeches and hearings work very well with RealPlayer. The RealPlayer is also ideal for the broadcast of real-time events. These may include press conferences, live radio and television broadcasts, concerts, etc.

Sound files, including music, may also be heard on the Web. It is not uncommon to visit a Web page and hear background music.

Live cams are another aspect of the multimedia experience available on the Web. Live cams are video cameras that send their data in real time to a Web server. These cams may appear in all kinds of locations, such as an office, on top of a building, a scenic locale, a special event, and so on. Text, audio and video communication can occur in real time on the Web. This capability allows people to conference and collaborate in real time. In general, the faster the Internet connection, the more successful the experience
