There are 2 services that you’ll need for a working site - a domain name plus a hosting plan for it. Whenever you type the domain in your Internet browser, you see the content that is uploaded in the web hosting account, but if that Internet domain is not linked to such an account or to an e-mail service, it's parked. Put simply, the domain name is registered and you're its owner, but it does not have any content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it can be forwarded to any other URL of your choice. The main advantage of parking a domain address is that you can keep it and make certain that nobody else will take it. Meanwhile, it will not take a slot for a hosted domain address in your account. You could also park domains 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 site as a way to protect a brand name.
