The two most popular Web browsers are Microsoft Internet Explorer and Netscape Navigator. A Web browser presents data in multimedia on Web pages that use text ， graphics ， sound and video.

..  The Web pages are created with a formal language called Hypertext Markup Language （ HTML ）.The term hypertext is used to describe an interlinked system of documents in which a user may jump from one document to another in a nonlinear way. Hyperlink makes the Internet easy to navigate. It is an object （ word ， phrase ， or picture ） on a Web page that ， when clicked ， transfers you to a new Web page.

FTP is designed to download files （ e. g.receive from the Internet ） or upload files （ e.g. send to the Internet ）.The ability to upload and download files on it is one of the most valuable features the Internet offers. This is especially helpful for those people who rely on computers for various purposes and who may need software drivers and upgrades immediately. Network administrators can rarely wait even a few days to get the necessary drivers that enable their network servers to function again. The Internet can provide these files immediately by using FTP.FTP is a client-server application just like and Telnet. It requires server software running on a host that can be accessed by client software.

It provides access to multiple services and documents as Gopher does but is more ambitious in its method. A jump to other Internet service can be triggered by a mouse click on a “hot-linked” word ， image ， or icon on the Web pages. One of the main reasons for the extraordinary growth of the Web is the ease in which it allows access to information. One limitation of HTTP is that you can only use it to download files ， and not to upload them.

To make a connection with a Telnet client ， you must select a connection option: “Host Name” and “Terminal Type”. The host name is the IP address （ DNS ） of the remote computer to which you connect. The terminal type describes the type of terminal emulation that you want the computer to perform.

.   5.BBS  Another interesting application for Internet is the Electronic Bulletin Board which is also called Bulletin Board Service ， BBS for short. It allows users to post and retrieve messages that are not directed to a specific user ， much like announcements are posted on an office bulletin board. BBS has been used for everything from dating services and want ads to highly specialized applications such as the exchange of research data in a narrow scientific field.
