There are 2 services that you need for a working site - a domain name and a web hosting plan for it. Any time you type the domain address in your Internet browser, you see the content that’s uploaded within the website hosting account, but if that domain address is not linked to such an account or to an email service, it's parked. Put simply, the domain name is registered and you are its owner, but it lacks content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” page from the registrar company, or it can be directed to any other URL of your choice. The main benefit of parking a domain name is that you can keep it and be sure that nobody else is going to take it. In the meantime, it will not take a slot for a hosted domain address inside your account. You can also park domain names if you have a .com, for example, and you register domain addresses with other extensions such as .net, .org or country-code ones to direct them to the main website in order to protect a brand name.
