== World Wide Web ==

The '''World Wide Web''' (often abbreviated as '''WWW''' or simply '''the Web''') is an information system that enables documents and other resources to be accessed via the [[Internet]]. It was invented by British scientist [[Tim Berners-Lee]] in 1989 while working at [[CERN]]. The Web is built on three core technologies: [[HTTP]] (Hypertext Transfer Protocol), [[HTML]] (Hypertext Markup Language), and [[URL]]s (Uniform Resource Locators). Unlike the Internet, which is a global network of interconnected computers, the Web is a service that runs on top of the Internet and allows users to navigate between linked pages using a [[Web browser]].

== History ==

The concept of the World Wide Web was first proposed by Tim Berners-Lee in March 1989 in a memorandum titled "Information Management: A Proposal". He envisioned a system that would allow researchers at CERN to share information easily using [[hypertext]]. The first website, info.cern.ch, went live on 6 August 1991. It described the project and explained how to create Web pages. In 1993, the release of the [[Mosaic (web browser)|Mosaic]] browser by Marc Andreessen and Eric Bina popularised the Web, making it accessible to a wider public. The [[World Wide Web Consortium]] (W3C), founded by Berners-Lee in 1994, continues to develop and maintain open standards for the Web.

== Features ==

The World Wide Web is characterised by several key features:

* '''Hypertext and Hyperlinks''': Documents are connected through [[hyperlink]]s, allowing users to navigate between resources with a single click.
* '''Graphical User Interface''': Modern web browsers display text, images, videos, and other media, enabling rich user experiences.
* '''Decentralised Architecture''': Any person or organisation can host a website without central approval, though domain names are managed by [[ICANN]].
* '''URL Scheme''': Every resource has a unique Uniform Resource Locator, which specifies its location and how to retrieve it.
* '''Client-Server Model''': Web browsers (clients) send HTTP requests to [[web server]]s, which return the requested content.

== Impact ==

Since its creation, the Web has revolutionised communication, commerce, education, and culture. It gave rise to [[social media]], [[e-commerce]], [[search engine]]s, and countless other services that have reshaped modern society. The Web's open standards and universal accessibility have made it a fundamental part of everyday life for billions around the world.
