There are two separate services that you’ll need for a working web site - a domain plus a web hosting plan for it. Each time you type the domain in your Internet browser, you see the content that’s uploaded within the web hosting account, but if that Internet domain isn't linked to such an account or to an email service, it's parked. To put it differently, the domain name is registered and you're its owner, but it lacks content of its own. As a substitute, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it may be forwarded to any other URL of your choice. The benefit of parking a domain name is that you can keep it and make sure that nobody else is going to take it. Meanwhile, it won't take a slot for a hosted domain name in your account. You may also park domain names if you have a .com, for example, and you register domains with other extensions such as .net, .org or country-code ones to forward them to the main web site so as to protect a brand name.
