If you wish to register a domain name to make sure that no one else is going to take it, however, you haven't built the website for it yet, you may park it. This is a feature that registrar companies provide whenever a domain address isn't linked to any web or e-mail hosting service. By doing this, you'll be able to protect a brand name, for instance, and you will own the domain address in question even though it won't load any content. If you wish, you can choose some standard template that the registrar provides, such as For Sale or Under Construction, or you can forward the domain name to a different web address. Your second option is very useful in case you own a number of domain names, but you want each and every one of them to open the same site. For instance, you could register domain.net and domain.org, then park them and forward them to domain.com. In this example, you are going to need hosting for the third domain only and the traffic to the other ones is going to be redirected to it.
