There are two services that you’ll need for a functioning site - a domain and a hosting plan for it. If you type the domain name in your Internet browser, you see the content that is uploaded within the hosting account, but if that Internet domain isn't linked to such an account or to an email service, it is 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. As a substitute, it can open either a pre-made “Under Construction / For Sale” page from the registrar company, or it may be directed to any other URL of your choice. The benefit of parking a domain is that you can keep it and make certain that no one else will take it. In the meantime, it will not occupy a slot for a hosted Internet domain inside your account. You could also park domains if you have a .com, for example, and you register domains with other extensions like .net, .org or country-code ones to direct them to the main website so as to protect a brand name.
