There are 2 services that you need for a working website - a domain name and a web hosting plan for it. Any time you type the domain address in your web browser, you see the content that’s uploaded inside the hosting account, but if that Internet domain isn't 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. As a substitute, it can open either a pre-made “Under Construction / For Sale” page from the registrar company, or it can be forwarded to some other URL of your choice. The benefit of parking a domain is that you can keep it and make sure that nobody else will take it. Meanwhile, it's not going to take a slot for a hosted Internet domain inside your account. You could also park domain names if you have a .com, for instance, and you register domain names with other extensions like .net, .org or country-code ones to direct them to the main website as a way to protect a brand name.
