There are two separate services you need for a functioning web site - a domain and a web hosting plan for it. When you type the Internet domain in your browser, you see the content that’s uploaded in the website hosting account, but if that domain address is not linked to such an account or to an email service, it is parked. In other words, the domain address 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” page from the registrar company, or it may be directed to some other URL of your choice. The advantage of parking a domain name is that you can keep it and make sure that no one else will take it. In the meantime, it will not occupy a slot for a hosted Internet domain inside your account. You can also park domain names if you have a .com, for instance, and you register domains with other extensions such as .net, .org or country-code ones to forward them to the main site so as to protect a brand name.
