There are two services that you’ll need for a working website - a domain plus a website hosting plan for it. If you type the Internet domain in your web browser, you see the content that is uploaded within the hosting account, but if that domain name isn't linked to such an account or to an e-mail service, it is parked. Put simply, the domain 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” page from the registrar company, or it could be forwarded to some other URL of your choice. The advantage of parking a domain is that you can keep it and ensure that nobody else will take it. In the meantime, it will not occupy a slot for a hosted domain name in your account. In addition, you can park domain names if you have a .com, for instance, and you register domain names 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.
