A parked domain address is one that is taken, yet it is not linked to another service - web or email hosting. Basically, this kind of domain address won't load any real content when you type it in a browser, but no one else can take it as you've already registered it and you are its owner. The benefit of acquiring a domain name and parking it afterwards is that you’ll be able to keep it and not stress that someone else could possibly register it meanwhile if, for instance, the site for it is not ready yet. You are able to set a temporary Under Construction website page for a parked domain while you are working on the site, or direct it to another web address - temporarily or permanently. The latter option can be employed when you have already registered domain.com, for instance, and you get domain.net and domain.org, in order to protect a brand name or a trademark. In this situation, the .net and .org domain addresses can be parked and directed to the .com because you don't need individual websites for them.
