A parked Internet domain is one that's taken, but it's not linked to another service - web or e-mail hosting. Basically, this type of domain name will not load any real content if you type it in a browser, but nobody can take it as you've already registered it and you are its owner. The advantage of acquiring a domain and parking it afterwards is the fact that you will be able to keep it and not stress that somebody else may register it meanwhile if, for instance, the site for it is not ready yet. You are able to set a temporary Under Construction page for a parked Internet domain while you're working on the web site, or forward it to some other web address - temporarily or permanently. The latter option can be employed if you have already registered domain.com, for instance, and you get domain.net and domain.org, so as to protect a brand name or a trademark. In cases like this, the .net and .org domains can be parked and forwarded to the .com because you do not need individual sites for them.
