History of World Wide Web Information System

The World Wide Web or simply "the Web" is a global information system that is the fastest-growing area of the internet. over 400 million specially formatted documents, known as web pages are linked via an information navigation scheme called hypertext.

History of World Wide Web Information System

The web-like all internet services is based on the interaction and transfer of data between special server computers that is web servers and your PC that is using web browser software such as internet explorer from Microsoft.

Hypertext (Non-linear Information)

Conventional information systems like textbooks present information on printed pages in a linear fashion. hypertext information systems, on the other hand, allow you to navigate through a flood of "information space" following any path of your choice.

Hypertext information systems, on the other hand, allow you to navigate through a flood of "information space" following any path of your choice. Hypertext, as implemented on the web, allows web pages to be created with links to any other page on the web. this system allows you to choose from various links on a single web page that typically leads to other web pages at different websites geographically located anywhere in the world.


Is the heart of the web is the ability to display multimedia information such as images, audio, video, animation, and other multimedia data types.


Hyperlinks or links are web navigation elements that allow you to move, or navigate, between web pages. they also allow you to download audio, video, and other types of multimedia files. web pages accessed via a link may reside at the same website as the source link or at another site anywhere on the web.

There are three types of hyperlinks.

  1. Text hyperlinks
  2. Image hyperlinks
  3. Image maps(containing multiple hyperlinks)

Functionally, all three categories of hyperlinks are identical. text hyperlinks are generally denoted in blue color and underlined, while image hyperlinks and maps are indicated by a blue-colored border. in all three cases, the mouse pointer will change from an arrow to a pointing hand when it passes over a hyperlink.

Elements of the Web

Web Browser

Web Pages vs Web sites

A web page is a part of a complete website. a novel in English literature is a good analogy, think of the difference between a single page and the entire novel and you can begin to understand the relationship between a web page and a website.

A novel in its totality is analogous to the website and an individual page is analogous to the web page. the website can consist of only a few web pages or many hundreds of web pages. for example Microsoft website currently server over 250,000 web pages.
