There are two separate services that you need for a working web site - a domain and a hosting plan for it. When you type the Internet domain in your Internet browser, you see the content that’s uploaded in the website hosting account, but if that domain isn't linked to such an account or to an e-mail service, it is parked. In other words, the domain address is registered and you are 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” webpage from the registrar company, or it may be directed to some other URL of your choice. The advantage of parking a domain address is that you can keep it and make certain that nobody else will take it. Meanwhile, it's not going to block a slot for a hosted domain address in your account. You can also park domains if you have a .com, for example, and you register domain names with other extensions such as .net, .org or country-code ones to forward them to the main website in order to protect a brand name.
