World Wide Web (WWW)

The World Wide Online (WWW), often known as the Web, is an information system in which Uniform Resource Locators (URLs) are used to identify documents and other digital resources. URLs, such as, which can be connected together via hyperlinks and are accessible over the Internet.

Hypertext Transport Protocol (HTTP) is used to transport Web resources, which are accessed by users via a web browser and published by a web server. The World Wide Web is not the same as the Internet, which is built on the same technology as the Web and predates it by more than two decades in certain forms.

A Brief History of WWW

The World Wide Web was founded in 1989 by Tim Berners-Lee, an English scientist. He invented the first web browser in 1990 while working at CERN in Geneva, Switzerland. The browser was first made accessible to other research organizations outside of CERN in January 1991, and then to the general public in August 1991. In the years 1993–2004, when websites for general use were available, the Web began to become more widely used. The World Wide Web is the tool that billions of people use to interact on the Internet, and it has played a key role in the development of the Information Age.

WWW vs Internet

The phrases "Internet" and the "World Wide Web" are often used interchangeably, but they do not have the same meaning. The Internet is a vast network of interconnected computer networks that span the globe. In comparison, the World Wide Web is a worldwide collection of papers and other resources connected together via hyperlinks and URIs. HTTP or HTTPS is an application-level Internet protocol that employs the Internet's transport protocols to access web resources.

Web browsers, Hypertext Markup Language (HTML), and Hypertext Transfer Protocol (HTTP) are among the technologies that make up the World Wide Web.

Normally, viewing a webpage on the World Wide Web begins with either inputting the page's URL into a web browser or clicking on a hyperlink to that page or resource. To fetch and display the requested page, the web browser sends a series of background communication messages.

Using a browser to read online pages—and to go from one web page to another via hyperlinks—became known as 'browsing,' 'web surfing,' or 'navigating the Web' in the 1990s. Early research on this new behavior focused on user behaviors when using web browsers. Exploratory surfing, window surfing, evolved surfing, constrained navigation, and focused navigation, for example, were discovered in one research.

Website Components

The Web is made up of three parts −

  • Uniform Resource Locator (URL) − serves as a system for resources on the Web.

  • HyperText Transfer Protocol (HTTP) − specifies communication of browser and server.

  • HyperText Markup Language (HTML) − defines structure, organization, and content of the webpage.
