Today you'll have the opportunity to find out the answers to four questions about the World Wide Web:
Netscape is a ``browser'' -- a program whose main purpose is to arrange and display on screen, for the benefit of a reader, the information and pictures that other people all over the world have made available through the Internet. Currently the World Wide Web consists of somewhere between eighty million and four hundred million such pages -- no one knows exactly how many.
There are browsers other than Netscape, including some designed for computers that cannot display graphics. (Such browsers have to use a short text description or simply the word `image' in place of each graphic.) However, as high-resolution color monitors become more common, even on personal computers, nearly all potential readers will use browsers as capable as Netscape.
Netscape underlines a word or phrase and displays it in a distinctive color to indicate that the reader can ``follow a link'' -- that is, direct Netscape to display a different text -- by moving the mouse-controlled pointer onto that word or phrase and pressing the left button on the mouse.
Try it for yourself: Bring up the next page of this presentation by moving the pointer onto the underlined phrase and clicking with the left button.
