A parked Internet domain is one which is taken, however it's not linked to another service - web or email hosting. To put it differently, such a domain will not load any real content when you type it in a web browser, but nobody else can take it as you have already registered it and you are its owner. The main advantage of acquiring a domain and parking it afterwards is that you’ll be able to keep it and not worry that someone else might register it in the meantime if, for example, the website for it is not ready yet. You may set a temporary Under Construction website page for a parked Internet domain while you're working on the website, or direct it to another web address - temporarily or permanently. The second option can be used if you have already registered domain.com, for example, and you get domain.net and domain.org, so that you can protect a brand name or a trademark. In this situation, the .net and .org domain names can be parked and forwarded to the .com as you do not need individual sites for them.
