There are two separate services you'll need for a working site - a domain plus a web hosting plan for it. If you type the Internet domain in your Internet browser, you see the content that’s uploaded in the hosting account, but if that domain isn't linked to such an account or to an e-mail service, it's parked. In other words, the 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” webpage from the registrar company, or it may be forwarded to any other URL of your choice. The main advantage of parking a domain address is that you can keep it and ensure that no one else is going to take it. At the same time, it won't occupy a slot for a hosted domain address inside your account. In addition, you can park domains 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 in order to protect a brand name.
