A parked domain address is one which is taken, but it is not linked to some other service - web or email hosting. In other words, this type of domain name won't load any real content if you type it in an Internet browser, but nobody can take it as you've already registered it and you are its owner. The best thing about getting a domain name and parking it afterwards is the fact that you are able to keep it and not stress that someone else might register it in the meantime if, for instance, the website for it is not ready yet. You can create a short-term Under Construction website page for a parked domain name while you're working on the web site, 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 such a case, the .net and .org domain names can be parked and directed to the .com because you don't need individual sites for them.
