A parked domain name is one that is taken, but it's not associated with some other service - web or e-mail hosting. Put simply, this type of domain will not open any real content when you type it in an Internet browser, but no one else can take it as you've already registered it and you are its owner. The main advantage of acquiring a domain name and parking it afterwards is that you will be able to keep it and not stress that someone else could possibly register it meanwhile if, for instance, the website for it is not ready yet. You are able to create a temporary Under Construction webpage for a parked Internet domain while you're working on your site, or direct 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 this situation, the .net and .org domain addresses can be parked and forwarded to the .com because you don't need separate sites for them.
