There are many different Web browsers available for almost every computer platform. The most popular is Netscape Navigator . One function of a Web browser is to interpret the address of a piece of information located on the Internet or World Wide Web. Browsers can find the information you seek because URLs provide directions to the computer and directories where a Web document is located, as well as its exact name and how it is to be accessed. Web browsers can access other protocols as well as Web protocols such as gopher, ftp, Usenet and others.
Browsers also retrieve requested information.
Browsers can also download or copy files, pictures, sounds and software for you to keep. World Wide Web pages are written and composed in the HTML page description language. What's more different browsers understand more or less sophisticated versions of the language. For that reason, a Web page will not always look the same on computers using different browsers. Some browsers, such as Lynx , are text-only browsers and will not display graphics at all.
