If you wish to make a web site, you need two things - a domain name and a hosting plan for it. The domain registration is the actual website address which you enter in a web browser to reach a website, while the hosting space is where your site files will be. These are 2 tightly related, but individual services, even though many people think that registering the domain is enough. Similar to the disk space and the monthly traffic features that a given web hosting plan has, there are a certain number of registered domain names that you can include as hosted which means that you can have the web content for them in some account even when the domains are in fact registered using a different provider. In technical terms, it does not matter if a domain name is registered and hosted with the same company or is registered with one company and pointed to another - either way your sites will operate the very same way.
