What Is the World Wide Web?

The World Wide Web refers to all the websites, documents and all other resources connected to the Internet and utilizing the hypertext transfer protocol (HTTP). This network also includes the computers and other devices accessing the Web's contents.

On March 12, 2014, the World Wide Web celebrated its 25th birthday at the Science Museum in London. During the celebration, a NeXT cube was displayed, letting people know that this single machine had given birth to what is now a network of more than 600 million websites. Sir Tim Berners-Lee is the British computer scientist who invented the Web. He runs the World Wide Web Foundation, which he founded.
