There are 2 services you'll need for a working web site - a domain and a website hosting plan for it. Any time you type the Internet domain in your browser, you see the content that’s uploaded within the web hosting account, but if that domain isn't linked to such an account or to an email service, it is parked. To put it differently, the domain address is registered and you are its owner, but it lacks content of its own. Rather, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it may be forwarded to some other URL of your choice. The main benefit of parking a domain is that you can keep it and make sure that no one else will take it. In the meantime, it won't block a slot for a hosted domain name inside your account. In addition, you can 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 site as a way to protect a brand name.
