A parked domain address is one that is taken, yet it is not linked to another service - web or e mail hosting. Essentially, this kind of domain will not open any actual content when you type it within a web browser, but nobody can take it as you've already registered it and you are its owner. The advantage of getting a domain name and parking it afterwards is that you are able to keep it and not stress that somebody else might register it in the meantime if, for example, the website for it is not ready yet. You are able to create a short-term Under Construction page for a parked domain name while you are working on your website, or forward it to another web address - temporarily or permanently. The latter option can be used when you have already registered domain.com, for instance, and you get domain.net and domain.org, so that you can protect a brand name or a trademark. In this situation, the .net and .org domains can be parked and directed to the .com as you don't need different websites for them.
