A parked domain is one that's taken, but it is not linked to some other service - web or e mail hosting. Basically, this type of domain address will not load any actual content in case you type it in a browser, but nobody can take it as you've already registered it and you are its owner. The best thing about acquiring a domain 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 instance, the site for it is not ready yet. You could create a short-term Under Construction website page for a parked Internet domain while you're working on your website, or forward it to another web address - temporarily or permanently. The second option can be employed when you have already registered domain.com, for example, and you get domain.net and domain.org, so that you can protect a brand name or a trademark. In this case, the .net and .org domains can be parked and forwarded to the .com as you do not need different websites for them.
