A parked Internet domain is one which is taken, but it's not associated with another service - web or e mail hosting. In other words, this type of domain name will not open any real content in case you type it within a web browser, but no one else can take it as you have already registered it and you are its owner. The benefit of obtaining a domain name and parking it afterwards is that you can keep it and not worry that somebody else might register it meanwhile if, for instance, the website for it is not ready yet. You may create a temporary Under Construction webpage for a parked domain while you are working on your site, or direct it to some other web address - temporarily or permanently. The second option can be used if you have already registered domain.com, for instance, and you acquire domain.net and domain.org, in order 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 since you don't need individual sites for them.
