There are 2 services that you need for a functioning website - a domain plus a hosting plan for it. Each time you type the domain in your web browser, you see the content that’s uploaded within the hosting account, but if that domain isn't 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 doesn't 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 could be forwarded to any other URL of your choice. The advantage of parking a domain is that you can keep it and make certain that no one else is going to take it. At the same time, it will not occupy a slot for a hosted Internet domain within your account. In addition, you can park domains if you have a .com, for instance, and you register domain names 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.
