A parked Internet domain is one that's taken, but it is not connected to any other service - web or email hosting. Essentially, this kind of domain address will not load any real content when you type it within a web browser, but no one else can take it as you have already registered it and you are its owner. The advantage of getting a domain and parking it afterwards is that you will be able to keep it and not worry that somebody else could possibly register it in the meantime if, for instance, the website for it is not ready yet. You may set a short-term Under Construction page for a parked domain while you're working on your site, or direct it to some other web address - temporarily or permanently. The latter option can be employed if you have already registered domain.com, for example, and you obtain domain.net and domain.org, so that you can protect a brand name or a trademark. In this case, the .net and .org domain addresses can be parked and forwarded to the .com as you do not need individual sites for them.
