Web server:

The World Wide Web (WWW) is a very popular Internet source of information. Web browsers present information to the user in hypertext format. When the user selects a word or phrase that a Web page’s author has established as a hypertext link, the Web browser queries another Web server or file to move to another Web page related to the link. For example, "Netscape" is a Web browser which queries Web servers on the Internet. Which Web server Netscape queries depends upon which hypertext link the user selects.
