A parked domain address is one that is taken, but it is not connected to another service - web or e-mail hosting. Essentially, this kind of domain address won't load any real content when you type it inside a browser, but no one else can take it as you have already registered it and you are its owner. The benefit of getting a domain and parking it afterwards is the fact that you will be able to keep it and not worry that someone else may register it meanwhile if, for example, the website for it is not ready yet. You can create a short-term Under Construction page for a parked domain name while you are working on your website, or forward it to some other web address - temporarily or permanently. The latter option can be used when you have already registered domain.com, for example, and you get 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 websites for them.
