Computer handshake. Abstract image of a handshake between a human and a computer against a backdrop of the Earth. Computers have improved global comm- unications due to the information superhighway. Computers are able to communicate with each other over telephone lines. An international network, the Internet, has been established for the free exchange of ideas and information. Part of this 'information superhighway' is the World Wide Web (WWW or Web). Users of the Web are able to navigate between computers to access text and pictures held in hypertext files.
