After reading this document and being extremely confused I gained the following information. “It is intended that after reading this article you will have an idea of what W3 is, where it fits in with other systems in the field, and where it is going. There is much more to be said, especially about providing information,but this is described on the Web itself. Also in the “Web about the Web” are lists contributed research and development work and ideas, and pointers to work in progress, so that those interested can work together.”

A W3 “client” program runs on your computer. When it starts it displays an object normally a document with text and possibly images. Some of the phrases and images are highlighted in blue, or boxed, or perhaps numbered, depending on what sort of a display you have and how your preferences have been set.
“Highlighted “anchor” causes the client program to retrieve another object from some other computer a “server” so the process of navigation continues. When viewing some documents, the reader can request a search, by typing in plain text (or complex commands) to send to the server, rather than following a link. In either case, the client sends a request off to the server often a completely different machine in some other part of the world, and within (typically) a second, the related information, in either hypertext, plain text or multimedia format, is presented. This is done repeatedly and by a sequence of selections and searches one can find anything that is “out there”
I assume it’s talking about the program and I just hope there’s not too much of this awful article on our final exam, it had way too much tech jargon which I cannot follow.
