There are 2 services that you’ll need for a working site - a domain plus a website hosting plan for it. Each time you type the Internet domain in your web browser, you see the content that’s uploaded within the website hosting account, but if that domain address is not linked to such an account or to an e-mail service, it's parked. To put it differently, the Internet domain is registered and you are its owner, but it does not 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 can be directed to some other URL of your choice. The benefit of parking a domain is that you can keep it and be sure that no one else is going to take it. In the meantime, it's not going to occupy 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 in order to protect a brand name.
