Documents on the WWW are often referred to as web pages . Web pages are displayed on special viewing software called browsers . The most popular browsers in use today are Netscape's Navigator and Microsoft's Internet Explorer. Web pages are often multimedia affairs, meaning that they combine text with graphics, still pictures, sound, animated graphics, and interactive applications. Hypertext refers to the way that web pages are interconnected through links .
Most browsers display links underlined and in a different colour than the rest of the text.
Using your browser to follow links from one page to another to the next to yet another is often referred to as surfing . You may surf quite happily across a large portion of the WWW and find all sorts of interesting information. Because the WWW is so decentralised and dynamic, no single authoritative index exists. There are, however, many indices and search engines that can help you find what you need. Some of the most popular of these indices and search engines are the following.
