If you want to register a domain name to ensure that nobody else will take it, but you haven't developed the site for it yet, you can park it. That is a feature that registrar companies offer when a domain isn't connected to any web or email hosting service. This way, you'll be able to protect a brand name, for instance, and you will own the domain in question even though it won't load any content. If you wish, you can select some default template that the registrar provides, such as For Sale or Under Construction, or you can forward the domain name to an alternative web address. Your second option is extremely helpful if you own a number of domains, but you want every one of them to open the same site. As an illustration, you could 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 address only and the traffic to the other ones will be redirected to it.
