If you want to make a web site, you need 2 things - your own domain name and a web hosting plan for it. The domain registration is the actual web address that you enter in a browser to access a site, while the hosting space is where your website files will be. These are 2 tightly related, yet independent services, while many people believe that registering the domain is enough. Much like the disk space and the monthly traffic features which a given website 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 are actually registered through a different service provider. In technical terms, it doesn't matter if a domain is registered and hosted using the same company or is registered with one company and pointed to another one - either way your websites will operate exactly the same way.
