There are 2 services that you need for a functioning website - a domain and a web hosting plan for it. Each time you type the Internet domain in your browser, you see the content that is uploaded in the website hosting account, but if that domain name isn't linked to such an account or to an email service, it's parked. To put it differently, the Internet domain 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” page from the registrar company, or it may be directed to some other URL of your choice. The advantage of parking a domain name is that you can keep it and make sure that no one else is going to take it. At the same time, it will not take a slot for a hosted domain address inside your account. In addition, you can park domains 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 web site in order to protect a brand name.
