A parked Internet domain is one which is taken, but it's not associated with any other service - web or email hosting. Basically, such a domain name won't load any real content if you type it in a browser, but no one can take it as you've already registered it and you are its owner. The best thing about getting a domain name and parking it afterwards is the fact that you will be able to keep it and not stress that someone else may register it in the meantime if, for instance, the site for it is not ready yet. You can create a short-term Under Construction website page for a parked domain address while you are working on your 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 obtain domain.net and domain.org, in order to protect a brand name or a trademark. In this situation, the .net and .org domain names can be parked and directed to the .com as you do not need different sites for them.
