Each computer site determines what kind of information it wants to store. Until recently, not very well. Various tools have been around for years, but you needed to be very computer literate to use them. Now, a new development called the World Wide Web is making great strides towards both organization and ease of use for the rest of us. The World Wide Web's user-friendly graphical interface, called a web browser, uses web pages and hyperlinks to present information to the viewer.
Web pages are typically a combination of text and graphics.
Hyperlinks are highlighted text and image components that, when selected, display other web pages. The interface is very similar to the help screens that are now so common within Windows and Macintosh software. When you move the arrow cursor over a highlighted area, the arrow turns into a hand. Press the mouse button and the hand leads you to a separate page of information about the highlighted subject. There is no single huge worldwide index or table of contents.
