2012 Second Grading Lecture 2



ELEMENTS OF A WEB SITE

Just like other windows, any web site has a title bar, a menu bar, and a toolbar. The title bar shows the current site being used while the menu bar shows available list command options like file, edit, view, favorites, tools and help. By clicking the Go button, one can go to the web site that appears in the address bar. On the right side of the window, the scroll bar appears where you can scroll up and down on the page.    

The browser window includes an Address Bar that shows the address of your current location. You can always type a new address into the Address field to check out a different Web site.

Lastly, the bottom of the window is a status bar. When you go to a Web page or Web site, the Internet Explorer might take a little time to access the page and display it for you. The status bar shows you where you are in the process while the connectivity icon shows when you are currently connected to Internet or not.

          Like the Word toolbar; however, the Internet Explorer Standard toolbar gives you access to the most commonly used options in the program .

            Back. The Back button returns you to the previous page. You can click it repeatedly to return to a page you have previously visited. The Back button goes back only to sites that you visited during your current session.
          Forward. The Forward button reverses the action of the Back button. If you go back to many pages, the Forward button enables you to move up to where you were. The Forward button goes forward only to sites that you visited during your current session.
          Stop. The Stop button stops a newly selected page from loading. When a page is taking a long time to load, or you see that it is not a page you want, clicking Stop will save you the time it would take to finish loading.
          Refresh. The Refresh button retrieves the page again and reloads it. If you are interested in pages that include information that is constantly being updated—real-time stock quotes, for example—the Refresh button updates the screen with the most current information available.
          Home.  No matter where you find yourself, the Home button brings you back to your home page, that is, the page Internet Explorer first opens to.
Search. The Search button helps you find subject matter when you don’t know where to look.
            Favorites. The Favorites button displays a list of Web sites to which you can go without typing the URL.
          History. The History button shows you all the sites you have visited, listed by date. If you click one of the entries, you jump right to that site.
          Channels. The Channels button offers a diverse selection of Web sites, categorized by topic.
          Full Screen. The Full Screen button enables you to view a maximized Web page without the menu showing.
          Mail. The Mail button helps you manage your e-mail.
          Print. The Print button enables you to print the current Web page.
          Edit. The Edit button enables you to edit the currently displayed page in Notepad.
Find. Although there isn’t a Find button on the Standard toolbar, you can press Ctrl+F to find text on a page.


UNIFORM RESOURCE LOCATOR (URL)

          This is the address that defines the route file on the web. URLs are typed into the browser to access Web pages. The URL contains protocol prefix and domain name. Sometimes, it also includes subdirectory names and file name. For instance,

          This retrieves the home page at Yahoo Web Site. The http:// is the Web Protocol prefix, and www.yahoo.com is the domain name.
