181 Browsers: The Information Tool There's a good chance that you will spend a good deal of time with an Internet browser once you get a taste of the Internet. The Internet browser, or Web browser, is a software tool that makes it possible for you to tap the information resources of the electronic world and to communicate with those living in the electronic world. The viewing area of a browser can be filled with documents containing any combination of text, images, motion video, and animation. The visual information can be enhanced with real-time audio. These various forms of communication are presented within HTML documents. The browser opens an HTML document and displays the information according to HTML instructions embedded in the document. The HTML document pulls together all the necessary elements, including image files, audio streams, and small programs, called applets. The browser accepts the applets, then interprets and executes them. These applets frequently contain the instructions for an animation sequence. Browsers can be used with or without an Internet connection; however, an Internet link is needed to access files other than those on your PC or your local area network. We will discuss browsers within the context of the Internet. Concepts and Features We interact with word processing, desktop publishing, presentation, spread-

sheet, and database software to create some kind of a document. Browser software is different in that there is no resulting document. Browsers let you retrieve and view information as well as interact with server computers. Compared to the other productivity tools, browsers are easy to use, almost intuitive. The Internet: A Public Network The vast majority of the Internet resources made available by-millions of participating networks can be accessed by anyone, anywhere. To take advantage of these resources, you will need a browser and an Internet connection. Internet Organization. Fortunately, the Internet has a straightforward organization. At the top of the organization are the Internet servers, the computers that provide on-demand distribution of information. Each server has one or more home pages. When you navigate to a particular Web site (perhaps that of your college), the first page you will normally view is the site's home page. Information on the Web, which may be graphics, audio, video, animation, and text, is viewed in pages. A Web page can contain text plus any or all of these multimedia elements. Internet Servers. The World Wide Web (WWW), or Web server, with its multimedia capability, has emerged as the dominant server type on the Internet. The FTP server facilitates the transfer of files between computers, and the Gopher servers provide a hierarchical store-house of information. FTP and Gopher sites are being rapidly integrated in the more user-friendly Web server format. Browsers accommodate informa-tion retrieval for any type of Internet server. Internet Applications. World Wide Web servers have emerged as the choice cruising the Internet; however, other not-so-user-friendly types of servers contain useful information stilI not available from World Wide Web sources. These systems, which pre-date the World Wide Web, include FTP, Gopher, Telnet and Webcasting. Critical resources on these servers are being reformatted and modernized for distribution via World Wide Web servers. This section describes modern and traditional servers on the Internet. WWW: World Wide Web. The World Wide Web, affectionately called

the Web, is an Internet system that permits linking of multimedia documents among servers on the Internet. By establishing a linked relationship between Web documents, related information becomes easily accessible. These linked relationships are completely independent of physical location. These attributes set Web servers apart from other Internet servers.

  • User-Friendly. Prior to the World Wide Web, most Internet users were techies and IT professionals. Web resources are designed to be accessed with Internet browsers. These easy-to-use browsers, with their graphical user interfaces, let users point-and-click their way around the Internet.
  • Multimedia Documents. A Web page is much more than a page in a book. It can contain all of these multimedia elements: graphics, audio, video, animation, and text.
  • Hyperlinks. Multimedia resources on the Web are linked via hyperlinks. Web documents are created using HTML (Hyper Text Markup Language). HTML is the 'tag' language used to format and transmit Web pages. Words and phrases within HTML documents (pages on the Web) can be marked (tagged) and highlighted to create interactive links to related text or multimedia information. Hyperlinks on the Web are displayed differently from accompanying text, usually as colored (often blue) and underlined text. Links need not be limited to text, though. Any multimedia object on the page (images, animated objects, and so on) can be a hyperlink. When the cursor is positioned over a hyperlink, it changes to a hand with a pointing finger. When you click on the link (the highlighted word[s] or image), you are electronically whisked away to the URL (uniform resource locator) address specified in the HTML document. The link could take you to another location in the same document or to another document on the same Web server or to a Web server on another continent. The transition between hyperlinks appears seamless to the Web user.
  • Interactive. The Web system, with its pages, enables interactivity between users and servers. There are many ways to interact with the Web. The most common form of interactivity is clicking on hyper-

links to navigate around the Internet. Some pages have input boxes into which you can enter textual information. You can click on radio buttons to select desired options. Radio buttons are circle bullets in front of user options that when selected include a dot in the middle of the circle. Each time you enter information in a text box or make selections. you will normally have to click on a submit button to transmit the information to the server computer.

  • Frames. Some Web sites present some or all of their information in frames. The frames feature enables the display of more than one independently controllable section on a single Web page. When you link to a Web page that uses frames, the URL of that page is that of a master HTML file that defines the size, position, and content of the frames. Ultimately your request for a frames page results in multiple HTML files being returned from the Web server. The frames capability may be used to display the main site options in one small frame and the primary information page in another larger frame. Sometimes a third frame displays context-sensitive instructions.

FTP: Downloads for the Asking. The File Transfer Protocol (FTP) allows you to download and upload files on the Internet. FTP has been around for a long time, so thousands of FTP sites offer millions of useful files-most are free for the asking. FTPing is a popular activity on the Net. Gopherspace: Go-For Information. Gopherspace is the home of thousands of Gopher servers throughout the world. The Gopher system, which pre-dates the World Wide Web, was developed at the University of Minnesota, the home of the Golden Gophers. Think of the Gopher system as a huge menu tree that allows you to keep choosing menu items until you find the information you want. Gopher resources can also be accessed through Internet browsers. Telnet: Remote Login. Telnet refers to a class of Internet application programs that lets you log into a remote computer using the Telnet communication protocol. Telnet is a terminal emulation protocol that allows you to work from a PC as if it were a terminal linked directly to a host computer. We b casting: Internet Broadcasting. Until recently, all Internet sites

were more or less passive, waiting for Net surfers to find them. It's now apparent that the Internet can be a broadcast medium as well. For example, thousands of radio stations now web cast their audio signals over the Internet.
