If you want to register a domain name to make certain that no one else will take it, however, you have not built the site for it yet, you may park it. It's a service that registrar companies provide whenever a domain address is not linked to any web or e-mail hosting service. That way, you can protect a brand name, for example, and you will own the domain name in question although it won't open any content. If you'd like, you may choose some default template that the registrar offers, such as For Sale or Under Construction, alternatively you can forward the domain name to a new web address. The 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 example, you could register domain.net and domain.org, then park them and forward them to domain.com. In this example, you'll need hosting for the third domain name only and the traffic to the other ones is going to be redirected to it.
