If you wish to register a domain name to make sure that nobody else will take it, but you have not created the site for it yet, you may park it. It's a service that registrar companies provide whenever a domain address isn't connected to any web or e mail hosting service. This way, you are able to protect a brand name, for example, and you'll own the domain name in question even though it won't open any content. If you want, you can select some standard template that the registrar provides, like For Sale or Under Construction, or you can forward the domain name to a new web address. The second option is very helpful in case you own a few domain names, but you want each and every one of them to open the same site. For instance, you may register domain.net and domain.org, then park them and forward them to domain.com. In this example, you're going to need hosting for the third domain name only and the traffic to the other ones will be redirected to it.
