There are two separate services that you’ll need for a working web site - a domain name plus a website hosting plan for it. Whenever you type the domain address in your Internet browser, you see the content that is uploaded within the website hosting account, but if that domain name isn't linked to such an account or to an email service, it's parked. Put simply, the domain address is registered and you are its owner, but it lacks 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 directed to some other URL of your choice. The benefit of parking a domain address is that you can keep it and be sure that no one else is going to take it. Meanwhile, it's not going to block a slot for a hosted Internet domain within 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 direct them to the main web site so as to protect a brand name.
