A parked domain name is one that's taken, but it's not linked to some other service - web or email hosting. Put simply, this kind of domain won't open any actual content when you type it inside an Internet browser, but nobody else can take it as you have already registered it and you are its owner. The advantage of acquiring a domain name and parking it afterwards is that you are able to keep it and not worry 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 webpage for a parked Internet domain while you're working on your website, or direct it to some other web address - temporarily or permanently. The latter option can be employed when you have already registered domain.com, for instance, and you obtain domain.net and domain.org, in order to protect a brand name or a trademark. In this situation, the .net and .org domains can be parked and directed to the .com since you do not need separate websites for them.
