There are 2 services that you need for a working website - a domain and a website hosting plan for it. Each time you type the domain address in your web browser, you see the content that is uploaded within the web hosting account, but if that Internet domain is not linked to such an account or to an e-mail service, it is parked. To put it differently, the domain address is registered and you are its owner, but it doesn't 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 can be forwarded to any other URL of your choice. The benefit of parking a domain name is that you can keep it and ensure that nobody else is going to take it. Meanwhile, it won't take a slot for a hosted Internet domain inside your account. You may also park domains if you have a .com, for instance, and you register domain addresses with other extensions such as .net, .org or country-code ones to forward them to the main web site as a way to protect a brand name.
