There are two services you'll need for a functioning website - a domain and a website hosting plan for it. Each time you type the Internet domain in your Internet browser, you see the content that is uploaded inside the hosting account, but if that domain address is not linked to such an account or to an email service, it is parked. Put simply, the domain name 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 may be forwarded to any other URL of your choice. The benefit of parking a domain name is that you can keep it and make sure that nobody else is going to take it. In the meantime, it won't block a slot for a hosted domain within your account. You may also park domains if you have a .com, for example, and you register domains with other extensions like .net, .org or country-code ones to direct them to the main site as a way to protect a brand name.
