There are two separate services that you’ll need for a working website - a domain name and a website hosting plan for it. Each time you type the domain in your browser, you see the content that is uploaded within the website hosting account, but if that domain is not linked to such an account or to an e-mail service, it is parked. In other words, the domain is registered and you're 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 could be directed to any other URL of your choice. The advantage of parking a domain is that you can keep it and make sure that nobody else is going to take it. Meanwhile, it will not occupy a slot for a hosted Internet domain inside your account. In addition, you can park domains if you have a .com, for instance, and you register domain addresses with other extensions like .net, .org or country-code ones to direct them to the main website so as to protect a brand name.
