A parked Internet domain is one that's taken, but it is not associated with any other service - web or email hosting. Put simply, such a domain won't load any actual content when you type it within an Internet browser, but no one else can take it as you've already registered it and you are its owner. The benefit of obtaining a domain name and parking it afterwards is that you’ll be able to keep it and not stress that someone else may register it in the meantime if, for instance, the website for it is not ready yet. You can create a short-term Under Construction page for a parked domain while you're working on the site, or direct it to some other web address - temporarily or permanently. The second option can be used when you have already registered domain.com, for instance, and you get domain.net and domain.org, so that you can protect a brand name or a trademark. In this case, the .net and .org domain names can be parked and directed to the .com because you don't need different websites for them.
