If you want 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 that you type in an Internet browser to reach a website, while the hosting space is where your website data will be. These are two very closely connected, yet separate services, even though many people assume that registering the domain is enough. Just like the disk space and the monthly traffic features which a given hosting plan offers, there are a certain number of registered domains which you can add as hosted which means that you can have the web content for them in some account even when the domains are actually registered via a different firm. In technical terms, it doesn't matter whether a domain is registered and hosted with the same company or is registered with one company and directed to another one - in any case your websites will function in exactly the same way.
