Web = Internet + Hypertext


The World Wide Web (commonly shortened to the Web) is a system of interlinked hypertext documents accessed via the Internet. With a Web explorer, one can view Web pages that may contain text, images, videos, and other multimedia contains and navigate between them using hyperlinks. The World Wide Web was created in 1989 by English scientist Tim Berners-Lee, working at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, and released in 1992. Since then, Berners-Lee has played an active role in guiding the development of Web standards, and in recent years has advocated his vision of a Semantic Web.


Hypertext, made famous by the World Wide Web, is most simply a way of constructing documents that reference other documents. Within a hypertext document, a block of text can be tagged as a hypertext link pointing to another document. When viewed with a hypertext explorer, the link can be activated to view the other document. Hypertext’s original idea was to take advantage of electronic data processing to organize large quantities of information that would otherwise overwhelm a reader.

The flexibility of hypertext gives free range to the author’s creativity, but good hypertext appears to have some common characteristics: Lots of documents. Much of the hypertext’s power comes from its ability to make large quantities of information accessible. Lots of links. If each document has just one link, then it is little more than normal, sequential text. A hypertext document should present the reader with several links, offering a choice about where to go next. Ideally, a document should present as many relevant links as the reader can easily comprehend and select among. Range of detail. The great advantage of hypertext is that it permits readers to explore to a breadth and depth that is simply not feasible in print. To make this accessible, available hypertext documents should range from the broadest possible overview of a subject, down to its gritty details. Correct links. This may seem trivial, but it’s amazing how many Web links point nowhere.


The terms “Internet” and “World Wide Web” are often used in every-day speech without much distinction or even as if they were the same. However, the Internet and the World Wide Web are not one and the same. The Internet is a global data communications system. It is a hardware and software infrastructure that provides connectivity between computers. In contrast, the Web is one of the services communicated via the Internet. It is a collection of interconnected documents and other resources, linked by hyperlinks and URLs


Aside from the complex physical connections that make up its infrastructure, the Internet is facilitated by bi- or multi-lateral commercial contracts and by technical specifications or protocols that describe how to exchange data over the network. Indeed, the Internet is defined by its interconnections and routing policies.  As of June 30, 2008, 1.463 billion people use the Internet according to Internet World Stats.


To get access to the Internet nowadays is so easy a mobile phone is enough.
