There are two services that you’ll need for a functioning website - a domain plus a website hosting plan for it. Each time you type the domain name in your browser, you see the content that is uploaded within the hosting account, but if that domain isn't linked to such an account or to an e-mail service, it's parked. Put simply, the Internet domain is registered and you're its owner, but it doesn't have any content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” Internet page from the registrar company, or it could be directed to some other URL of your choice. The benefit of parking a domain is that you can keep it and make certain that nobody else is going to take it. At the same time, it won't occupy a slot for a hosted Internet domain in your account. You could also park domain names if you have a .com, for instance, and you register domain addresses with other extensions like .net, .org or country-code ones to forward them to the main web site in order to protect a brand name.
