There are two separate services you'll need for a working website - a domain plus a web hosting plan for it. Whenever you type the domain in your browser, you see the content that is uploaded inside the web hosting account, but if that domain name is not linked to such an account or to an email service, it's parked. Put simply, the Internet domain is registered and you are its owner, but it lacks content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” Internet page from the registrar company, or it can be forwarded to any other URL of your choice. The advantage of parking a domain name is that you can keep it and make sure that nobody else is going to take it. At the same time, it won't take a slot for a hosted domain in your account. You could also park domain names if you have a .com, for example, and you register domain addresses with other extensions such as .net, .org or country-code ones to direct them to the main web site so as to protect a brand name.
