If you want to register a domain name to ensure that no one else will take it, however, you haven't developed the web site for it yet, you can park it. That 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 name in question although it will not load any content. If you wish, you can select some standard template that the registrar offers, such as For Sale or Under Construction, alternatively you can forward the domain name to a different web address. The second option is very useful in case you own a number of domain names, but you want all of them to open the same site. For example, you can register domain.net and domain.org, then park them and forward them to domain.com. In this example, you will need hosting for the third domain only and the traffic to the other ones will be redirected to it.
