In order to create a web site, you need 2 things - your own domain and a website hosting plan for it. The domain registration is the actual web address which you enter in a web browser to reach a website, while the hosting space is where your website files will be. These are two tightly connected, but individual services, even though many people think that registering the domain name is enough. Much like the disk space and the monthly traffic features which a given web hosting plan provides, there are a certain number of registered domain names that you can add as hosted i.e. you can have the web content for them in some account even when the domains are actually registered using a different provider. In technical terms, it does not matter if a domain is registered and hosted with the exact same company or is registered with one company and directed to another one - either way your websites will operate in exactly the same way.
