A parked Internet domain is one that is taken, but it is not connected to another service - web or e mail hosting. To put it differently, this type of domain will not load any real content in case you type it within an Internet browser, but no one else can take it as you've already registered it and you are its owner. The main advantage of obtaining a domain and parking it afterwards is the fact that you will be able to keep it and not stress that someone else may register it meanwhile if, for instance, the website for it is not ready yet. You can set a short-term Under Construction page for a parked domain name while you're 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 acquire domain.net and domain.org, so as to protect a brand name or a trademark. In cases like this, the .net and .org domains can be parked and directed to the .com as you don't need different websites for them.
