World Wide Web

The World Wide Web (also known as WWW, W3, or simply the Web) is a global interconnected information system that enables content sharing over the Internet. It facilitates access to documents and other web resources according to specific rules of the Hypertext Transfer Protocol (HTTP). The Web was invented by English computer scientist Tim Berners-Lee while at CERN in 1989 and opened to the public in 1993. It was conceived as a "universal linked information system".
