The World Wide Web consists of millions of documents, images,
sounds, movies and databases linked together to form a...ummm...
web. Just point and click at a hypertext link and you could be
whisked around the world (or dragged slowly and painfully across
the trans-Pacific cable, depending on the network load)
There's lots of useful stuff out there on the WWW (and lots
of kindly people creating virtual libraries, indexes and robots to help you
find them)
