There are two services that you’ll need for a working site - a domain name plus a hosting plan for it. Any time you type the Internet domain in your browser, you see the content that’s uploaded within the web hosting account, but if that Internet domain isn't linked to such an account or to an email service, it's parked. In other words, the domain name is registered and you're its owner, but it does not 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 forwarded to any other URL of your choice. The benefit of parking a domain is that you can keep it and make sure that nobody else will take it. Meanwhile, it will not block a slot for a hosted Internet domain inside your account. You can also park domains if you have a .com, for instance, and you register domains with other extensions such as .net, .org or country-code ones to forward them to the main web site in order to protect a brand name.
