There are 2 services that you need for a functioning web site - a domain name and a web hosting plan for it. Any time you type the Internet domain in your 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 email service, it is parked. Put simply, the domain name is registered and you're its owner, but it does not have any content of its own. Rather, 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 main advantage of parking a domain name is that you can keep it and make sure that no one else is going to take it. Meanwhile, it will not block a slot for a hosted domain name in your account. You may also park domain names if you have a .com, for instance, and you register domain addresses with other extensions such as .net, .org or country-code ones to forward them to the main website so as to protect a brand name.
