There are two services that you need for a working web site - a domain and a website hosting plan for it. Whenever you type the domain in your browser, you see the content that’s uploaded within the website hosting account, but if that domain address isn't linked to such an account or to an email service, it's parked. Put simply, the domain is registered and you're its owner, but it lacks 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 benefit of parking a domain address is that you can keep it and make sure that no one else will take it. In the meantime, it won't block a slot for a hosted Internet domain within your account. You can also park domains if you have a .com, for example, and you register domain names with other extensions like .net, .org or country-code ones to forward them to the main website as a way to protect a brand name.
