If you wish to register a domain to make sure that nobody else is going to take it, however, you have not built the website for it yet, you may park it. This is a feature that registrar companies offer whenever a domain address is not connected to any web or email hosting service. That way, you are able to protect a brand name, for instance, and you will own the domain address in question even though it will not open any content. If you would like, you can pick some standard template that the registrar offers, such as For Sale or Under Construction, or you can direct the domain to a different web address. The second option is very useful if you own a number of domain names, but you want every one of them to open the same site. As an illustration, you may register domain.net and domain.org, then park them and direct them to domain.com. In this example, you'll need hosting for the third domain only and the traffic to the other ones is going to be redirected to it.
