There are two separate services you'll need for a working web site - a domain name and a website hosting plan for it. Whenever you type the domain name in your Internet browser, you see the content that is uploaded within the web hosting account, but if that Internet domain isn't linked to such an account or to an e-mail service, it is parked. In other words, the Internet domain is registered and you are 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 main benefit of parking a domain name is that you can keep it and make sure that nobody else will take it. Meanwhile, it's not going to occupy a slot for a hosted Internet domain in your account. You can also park domain names if you have a .com, for example, and you register domains with other extensions like .net, .org or country-code ones to forward them to the main web site so as to protect a brand name.
