The internet is a huge network of computers all connected together, but it was the world wide web that made the technology into something that linked information together and made it accessible to everyone. In essence, the world wide web is a collection of webpages found on this network of computers – your browser uses the internet to access the world wide web.
The world wide web was invented by Sir Tim Berners-Lee in 1989 – originally he was trying to find a new way for scientists to easily share the data from their experiments. Hypertext (text displayed on a computer display that links to other text the reader can immediately access) and the internet already existed, but no one had thought of a way to use the internet to link one document directly to another.
Berners-Lee created the world wide web while he was working at CERN, the European Organization for Nuclear Research in Switzerland. His vision soon went beyond a network for scientists to share information, in that he wanted it to be a universal and free 'information space' to share knowledge, to communicate, and to collaborate. You can find out more about how his work on the world wide web at CERN began, here.
There are three main ingredients that make up the world wide web. URL (uniform resource locator), which is the addressing scheme to find a document; HTTP (hypertext transfer protocol), which connects computers together; and HTML (hypertext markup language), which formats pages containing hypertext links.
Berners-Lee also made the world’s first web browser and web server. During the 1990s the amount of web browsers being produced rapidly multiplied and a whole load more web-based technologies started sprouting up. To get a sense of how the world wide web has developed since its creation, check out this video below:
The world wide web opened up the internet to everyone, not just scientists. It connected the world in a way that made it much easier for people to get information, share, and communicate. It has since allowed people to share their work and thoughts through social networking sites, blogs, video sharing, and more.
