There are two separate services you need for a working web site - a domain plus a web hosting plan for it. When you type the domain address in your browser, you see the content that is uploaded in the web hosting account, but if that Internet domain is not linked to such an account or to an e-mail service, it's parked. Put simply, the domain is registered and you're its owner, but it doesn't have any content of its own. Rather, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it could be directed to any other URL of your choice. The advantage of parking a domain address is that you can keep it and ensure that no one else will take it. In the meantime, it will not occupy a slot for a hosted Internet domain within your account. You can also park domains if you have a .com, for instance, and you register domain names with other extensions like .net, .org or country-code ones to forward them to the main web site as a way to protect a brand name.
