A parked Internet domain is one that's taken, but it's not associated with any other service - web or email hosting. Essentially, this type of domain won't open any actual content in case you type it in an Internet browser, but nobody can take it as you've already registered it and you are its owner. The best thing about getting a domain and parking it afterwards is the fact that you will be able to keep it and not stress that somebody else could possibly register it meanwhile if, for instance, the site for it is not ready yet. You may create 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 acquire 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 because you do not need different sites for them.
