These addresses provide a direct link to a particular Web page. Instead of clicking links to try to find your way to a page, you can tell your browser the URL and say go get this page . Most browsers have a bar near the top in which you can type the URL of the page you want to go to.

The bar s almost certainly already displayed; it s a long text box.

If you don none none t want the bar there all the time (after all, it takes up room that is sometimes better given to the Web pages), you can leave it turned off. If you keep it turned off, you can generally use a shortcut key to display a dialog box in which you can type a URL. In Netscape, press Ctrl+O to open the box (or try Ctrl+L if that doesn t work; the shortcut key varies between versions); in Internet Explorer, choose File, Open or press Ctrl+O.

Internet Explorer 4 and later have a new feature. Click the Fullscreen button (or press F11) to remove almost all the controls (except a small toolbar at the top of the window), giving the Web page the maximum room.

You can even remove the small toolbar using an Autohide feature similar to that used by the Windows taskbar (right-click the toolbar and select Autohide).

com/newsltr/instruct/subsplain.htm Each part of this URL has a specific meaning: http:// This part tells the browser that the address is for a Web page. The http:// stands for Hypertext Transfer Protocol, the system used on the Internet to transfer Web pages.

/newsltr/instruct/ This part is the directory in which the Web server has to look to find the file you want.

In this example, the Web server has to look in the instruct directory, which is a subdirectory of the newsltr directory.

This part is the name of the file you want, the Web page. These files are generally .HTM or .

HTML files (that extension stands for Hypertext Markup Language, the coding used to create Web pages). Sometimes the URL has no filename at the end; in that case, the Web server generally sends a default document for the specified directory..
