There are two separate services you need for a functioning web site - a domain plus a web hosting plan for it. If you type the domain name in your browser, you see the content that’s uploaded within the web hosting account, but if that Internet domain isn't linked to such an account or to an email service, it is parked. In other words, the domain name is registered and you're its owner, but it doesn't have any content of its own. As a substitute, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it may be directed to any other URL of your choice. The advantage of parking a domain is that you can keep it and make certain that nobody else is going to take it. Meanwhile, it will not occupy a slot for a hosted Internet domain in your account. You could also park domain names if you have a .com, for example, and you register domain names with other extensions such as .net, .org or country-code ones to direct them to the main site as a way to protect a brand name.
