There are two separate services that you’ll need for a functioning web site - a domain and a hosting plan for it. If you type the Internet domain in your web browser, you see the content that is uploaded in the website hosting account, but if that domain is not linked to such an account or to an e-mail service, it's parked. To put it differently, the Internet domain 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” page from the registrar company, or it could be directed to some other URL of your choice. The benefit of parking a domain name is that you can keep it and make certain that nobody else is going to take it. At the same time, it will not occupy a slot for a hosted domain inside your account. You can also park domain names if you have a .com, for example, and you register domain names with other extensions like .net, .org or country-code ones to direct them to the main site as a way to protect a brand name.
