In order to create a web site, you need 2 things - a domain and a web hosting plan for it. The domain registration is the actual website address that you type in a browser to reach a website, while the hosting space is where your site files will be. These are 2 closely related, but individual services, while many people believe that registering the domain is enough. Very similar to the disk space and the monthly traffic features that a given website hosting plan has, there are a certain number of registered domains that you can include as hosted which means that you can have the web content for them in some account even when the domains are in fact registered via a different service provider. In technical terms, it does not matter if a domain name is registered and hosted with the same company or is registered with one company and pointed to another one - in either case your sites will operate in exactly the same way.
