A parked Internet domain is one that is taken, yet it is not connected to some other service - web or e mail hosting. Essentially, this kind of domain address will not load any actual content in case you type it inside a browser, but no one can take it as you have already registered it and you are its owner. The advantage of acquiring a domain and parking it afterwards is that you are able to keep it and not stress that someone else may register it meanwhile if, for example, the site for it is not ready yet. You could set a short-term Under Construction website page for a parked domain name while you are working on your site, or direct it to another web address - temporarily or permanently. The second option can be used when 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 addresses can be parked and forwarded to the .com since you don't need separate websites for them.
