What is a Domain Name
From MDSupportWiki
A Domain Name is much like a trademark or a license. It allows people to find your website by name instead of by number. It also allows customers to have a much more professional look because their website can be http://www.THEIRBUSINESSNAME.com instead of http://www.PROVIDERNAME.com/businessname. There can only be one of any Domain name in the world. If http://www.myweb.com is already registered by another company, then you must find a name that is not yet registered.
