World Wide Web or WWW or W3 is over the Internet retrievable system of electronic hypertext documents, through hyperlinks and about the HTTP or HTTPS protocols. To use the World Wide Web a Web browser needs ata from the Web server and fetches as screen display. The user can follow the links in the document that refer to other documents, whether they are stored on the same server or another. This results in a global network of websites. Tracking the hyperlink is often referred to as Internet surfing.
How World Wide Web or WWW Works
The WWW is in common usage, often synonymous with the Internet, although it is younger and only provides one of several possible uses of the Internet. There are other Internet services that are not integrated into the Web like IRC and telnet. As said by Tim Berners-Lee , the World Wide Web (W3) is a wide-area hypermedia information retrieval initiative aiming to give universal access to a large universe of documents.
World Wide Web is different from contemporary hypertext systems. World Wide Web requires only unidirectional links rather than bidirectional, making it possible to put a link to a resource without requiring intervention from its owner. Moreover, unlike other protocols, such as HyperCard or Gopher, World Wide Web is built in an way, which made the development of servers and clients without the restrictions of licenses.
Operation of World Wide Web
The World Wide Web is based on three core standards, HTTP as a protocol by which the browser information from the web server may ask for, HTML as a document description language that defines how the information is structured and how the documents are linked ( hyperlinks ), URLs as a unique identifier of a resource in the links is used.
Other standards of World Wide Web (W3) were added later, like Cascading Style Sheets (CSS) to create the appearance of the elements of a website.
The World Wide Web / W3C and other initiatives are to drive the development, therefore, in the direction of XHTML / XML, and CSS forward to regain the advantages of HTML. The ongoing efforts by the accessibility of Internet sites support this trend.
