There are two services you'll need for a working web site - a domain name plus a web hosting plan for it. Whenever you type the Internet domain in your Internet browser, you see the content that’s uploaded inside the web 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 domain name is registered and you are its owner, but it does not have any content of its own. As a substitute, it can open either a pre-made “Under Construction / For Sale” Internet page from the registrar company, or it may be directed to any other URL of your choice. The advantage of parking a domain address is that you can keep it and be sure that nobody else is going to take it. At the same time, it won't occupy a slot for a hosted domain in your account. You may also park domain names if you have a .com, for instance, and you register domain addresses with other extensions like .net, .org or country-code ones to direct them to the main web site in order to protect a brand name.
