Example 1 A First Look at Netscape Navigator and the World Wide Web
In going through the steps of this example, we'll start the browser, explain some of the items you'll see on your screen, and then look at one of the many directories available that give easy access to a lot of information on the WWW. We'll follow these steps: 
  1. Start Netscape Navigator.
  2. Click on the item labeled Search in the navigation bar.
  3. Explore the WWW.
  4. Exit Netscape Navigator.

1. Start Netscape Navigator.
 
Double-click on the Netscape icon. 

The first document you see is called the home page. When you're browsing the Web the home page is your starting point. The term home page also has another meaning. When individuals, organizations, or companies want to have a presence on the WWW or want to make information available on the WWW, they create a home page. In that sense the home page acts as a contact point or starting point for the connection between that individual, organization, or company and the rest of the World Wide Web. When you start Netscape you're likely to see the home page for Netscape Communications Corporation

2. Click on the item labeled Search in the navigation toolbar.
You can also retrieve the page by typing the URL for Yahoo in the location field.
To do that click on the location field, it will change color,
then type http://www.yahoo.com and press Enter

 
There's lots of information on the WWW and it's just about impossible to keep track of it all. To help, some folks have collected hyperlinks and arranged them into categories to create directories. Several are listed on the Netscape Net Search page. If Yahoo! isn't the one that's displayed, find it somewhere else on the page or type its URL http://www.yahoo.com 

3. Explore the WWW.
 
To explore the WWW, all you have to do is follow hyperlinks. Starting with a directory like this one, there's plenty of exploring to do. To be specific, click on the item Science from the list of topics. 

You can see there are still many topics to explore. Again, to be definite, select the hyperlink labeled Astronomy There are lots of links to follow here, and you can follow these or any links to explore the WWW. You'll find you can move from page to page easily with a little practice. Remember to press the Toolbar icon to go back through previous pages. 

 

4. Exit Netscape Navigator.
 
Click on File in the Menu Bar and then click on Exit

If you're using dial-up networking (using a modem with a SLIP/PPP connection), then ending the session will probably end your connection to the Internet. If you're paying by the minute or hour for the connection and you're done working with the Internet for the time being, be sure your connection is terminated. 

End of Example 1    



 

Having some problems?

Here's a list of error codes (and explanations) that you might see when you try to access a resource and somehow things just don't go exactly right. The list comes from Intranet FAQ 

Another list of error codes is available at CNET resources - tech central - technical advisers - Errors 


Example 2 Retrieving a Web page by Typing in a URL
When you're working on the WWW you may want to visit a Web page that isn't listed as a hyperlink in the document you're browsing. To do that you go to the Web page (actually you bring it to you) by typing the URL in the location field rather than by selecting a hyperlink. 

Here are the steps to follow in this example. 

  1. Start Netscape Navigator.
  2. Open a Document or open the URL http://www.city.net.
  3. Follow a hyperlink to information about South America by clicking on a region a map.
  4. Follow a series of text hyperlinks to get to information about Rio de Janeiro.
  5. Exit Netscape Navigator.
  1. Start Netscape Navigator.

2. Go to the Web page with URL http://www.city.net.

3. Follow a hyperlink to information about South America by clicking on a region on a map.

    Click one the region of the map labeled South America 
    That brings up a map of South America. 

    Now click on the region of the map labeled Brazil 

     
4. Follow a series of text hyperlinks to find information about Rio de Janeiro.
 
Now, get on to some Web pages with further information about Brazil and Rio de Janeiro. 

Click on the hyperlink cities under the heading Destinations. Alternatively, you can click on Rio de Janeiro on the map of the cities listed to the right of the map. 

Click on the hyperlink Rio de Janeiro

You're on your own now. Follow any of the hyperlinks on this or other Web pages to get some information about Rio de Janeiro or other places. 
 

5. Exit Netscape.
