A parked domain name is one that's taken, yet it is not linked to some other service - web or email hosting. Essentially, such a domain address won't open any real content when you type it within a browser, but nobody else can take it as you've already registered it and you are its owner. The best thing about obtaining a domain name and parking it afterwards is the fact that you’ll be able to keep it and not stress that somebody else could possibly register it in the meantime if, for instance, the site for it is not ready yet. You are able to create a temporary Under Construction webpage for a parked domain name while you are working on the site, or forward it to some other web address - temporarily or permanently. The second option can be used when you have already registered domain.com, for example, and you get domain.net and domain.org, so as to protect a brand name or a trademark. In cases like this, the .net and .org domains can be parked and directed to the .com because you don't need separate websites for them.
