World Wide Web. Representation of some of the types of data available on the World Wide Web (WWW or Web). A man is seen surrounded by images from the Web, illustrating the diversity of scientific and historic information available. Just above centre is a diagram showing the flow of Internet data across the NSFNET, the principal data network in the USA. At centre is a map of global sea surface temperatures gathered by the TOPEX satellite; just right of this is a diagram of a particle collision event. Near bottom left is a portrait of the mathematician Ada Lovelace. At lower centre is the logo of CERN, the European particle physics lab where the Web was developed.
