In order to create a web site, you need 2 things - a domain name and a hosting plan for it. The domain registration is the actual web address which you enter in a browser to reach a site, while the hosting space is where your site files is going to be. These are two tightly related, yet individual services, although many people believe that registering the domain name is enough. Similar to the disk space and the monthly traffic features which a given web hosting plan offers, there are a certain number of registered domain names you can add as hosted which means that you can have the web content for them in some account even when the domains have been registered via a different firm. In technical terms, it doesn't matter whether a domain name is registered and hosted with the same company or is registered with one company and pointed to another - in either case your websites will function in exactly the same way.
