There are two services that you’ll need for a functioning website - a domain plus a website hosting plan for it. Whenever you type the domain in your browser, you see the content that’s uploaded inside the hosting account, but if that domain address isn't linked to such an account or to an e-mail service, it's parked. Put simply, the Internet domain is registered and you are its owner, but it does not have any content of its own. Rather, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it could be directed to any other URL of your choice. The benefit of parking a domain is that you can keep it and make certain that no one else will take it. At the same time, it's not going to take a slot for a hosted domain 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 forward them to the main web site in order to protect a brand name.
