There are two services you need for a working website - a domain and a website hosting plan for it. Each time you type the domain in your Internet browser, you see the content that is 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 Internet domain is registered and you're its owner, but it lacks content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it can be directed to any other URL of your choice. The benefit of parking a domain address is that you can keep it and ensure that nobody else is going to take it. At the same time, it won't block a slot for a hosted domain address within your account. In addition, you can park domains if you have a .com, for instance, and you register domain names with other extensions like .net, .org or country-code ones to forward them to the main web site so as to protect a brand name.
