Navigating from web page to web page using hyperlinks
We mentioned earlier that hyperlinks can be added to almost any element on a typical web page including to text, graphics, pictures, animations, etc. By clicking on any hyperlink, you will be transported to another web page containing information related to the hyperlink in question. You will almost always know when an element on a web page is a hyperlink because your normal arrow cursor changes into a pointing hand. What is more, text hyperlinks are generally blue in colour and underlined, although this does not have to be the case (it depends to some extent on the person designing the web page in question).
It is extremely important to enter the URL correctly with respect to case, spelling and punctuation, otherwise you will get an error message saying that the domain name could not be found.
When you select (click on) a particular hyperlink, it changes colour indicating that it is a ‘visited link’ (ie. a hyperlink that you have clicked on).
When you get an error message, it is likely that you have entered the URL incorrectly into the location box – first double check the address you have entered to ensure tht it is correct. If it is correct, try retyping the address and pressing ‘Enter’ again (or without retyping the address, press the refresh button at the top of the browser). If you again get an error message, try connecting to a well-known web site such as http://www.cnn.com or http://www.microsoft.com. If you do get through, it suggests that there might be a problem with the original web site you were looking for (assuming your URL was correct) – maybe their server is down.
