A parked domain name is one that is taken, yet it is not associated with some other service - web or e mail hosting. In other words, such a domain name will not load any actual content if you type it in a browser, but no one can take it as you have already registered it and you are its owner. The advantage of obtaining a domain and parking it afterwards is that you can keep it and not worry that someone else may register it meanwhile if, for example, the site for it is not ready yet. You can set a short-term Under Construction website page for a parked domain name while you are working on your web site, or forward it to some other web address - temporarily or permanently. The second option can be employed if 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 situation, the .net and .org domains can be parked and forwarded to the .com as you do not need separate websites for them.
