Not sure exactly what you're asking - however:

Scenario 1 - you've bought a domain name and you've got a hosting account with (say) hostgator.com but when you type in the domain name, it shows a "you have successfully registered your name" ...

You have to know that your hosting company gives you nameserver information when you ordered the hosting and you need that information.

Log in to the website where you bought the domain name; find the bit in their domain control panel which says something like "update nameservers" and put in the information from hostgator into each of two fields and click the "update nameservers" button. The information will look something like NS1.hostgator.com and NS2.hostgator.com

Scenario 2 - you've already got the hosting and domain name working correctly, you've published the main page of your site and you need to link to other pages. (Either that or you are hoping to link to some interesting content you've found on the internet).

is the very basic format.

If you use a pc, you can see how other sites achieve this by viewing the source code of a page. By right-clicking on a blank bit of the page, you will get a small popup window with a menu - and towards the bottom of the box is a link which says "view source" - that gives you a whole pile of web code. Examine it carefully and see how it is achieved.

I hope that helps you - if it doesn't answer your question, please give us an example of what you'd like to achieve and we'll have another go
