There are two services you'll need for a functioning site - a domain and a web hosting plan for it. When you type the domain address in your Internet browser, you see the content that is uploaded within the website hosting account, but if that Internet domain is not linked to such an account or to an email service, it's parked. Put simply, the Internet domain is registered and you are 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 can be directed to any other URL of your choice. The main benefit of parking a domain address is that you can keep it and make sure that nobody else will take it. In the meantime, it will not block a slot for a hosted domain address inside your account. You can also park domain names if you have a .com, for instance, and you register domain addresses with other extensions such as .net, .org or country-code ones to forward them to the main web site in order to protect a brand name.
