There are two services that you’ll need for a functioning site - a domain plus a web hosting plan for it. Each time you type the domain in your browser, you see the content that’s uploaded within the website hosting account, but if that domain name isn't linked to such an account or to an e-mail service, it's parked. To put it differently, the domain address is registered and you're its owner, but it doesn't 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 could be forwarded to some other URL of your choice. The advantage of parking a domain address is that you can keep it and make certain that nobody else will take it. Meanwhile, it won't block a slot for a hosted Internet domain inside your account. You can also park domains if you have a .com, for example, and you register domain addresses with other extensions such as .net, .org or country-code ones to direct them to the main website so as to protect a brand name.
