There are 2 services you need for a functioning website - a domain and a website hosting plan for it. When you type the domain name in your web browser, you see the content that’s uploaded inside the web hosting account, but if that domain isn't linked to such an account or to an e-mail service, it's parked. In other words, the Internet domain is registered and you're its owner, but it lacks content of its own. Rather, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it may be directed to some other URL of your choice. The benefit of parking a domain name is that you can keep it and make sure that no one else is going to take it. In the meantime, it won't take a slot for a hosted domain name within your account. In addition, you can park domain names if you have a .com, for instance, and you register domain names with other extensions like .net, .org or country-code ones to direct them to the main web site as a way to protect a brand name.
