If you want to register a domain name to ensure that no one else will take it, but you haven't built the website for it yet, you can park it. It's a service that registrar companies offer whenever a domain address isn't linked to any web or email hosting service. That way, you are able to protect a brand name, for instance, and you will own the domain name in question although it won't open any content. If you wish, you may choose some standard template that the registrar provides, such as For Sale or Under Construction, alternatively you can forward the domain name to another web address. Your second option is extremely helpful if you own a few domain names, but you want every one of them to open the same site. As an illustration, you may register domain.net and domain.org, then park them and direct them to domain.com. In this example, you'll need hosting for the third domain address only and the traffic to the other ones will be redirected to it.
