If you wish to create a web site, you need two things - a domain and a web hosting plan for it. The domain registration is the actual web address which you enter in a web browser to access a website, while the hosting space is where your website data will be. These are two very closely connected, but independent services, although many people think that registering the domain is enough. Just like the disk space and the monthly traffic features which a given web hosting plan provides, there are a certain number of registered domains that you can add as hosted which means that you can have the web content for them in some account even if the domains have been registered via a different firm. In technical terms, it doesn't matter if a domain name is registered and hosted using the same company or is registered with one company and directed to a different one - in either case your sites will operate exactly the same way.
