If you wish to create a website, you need 2 things - a domain and a web hosting plan for it. The domain registration is the actual website address that you type in a web browser to access a site, while the hosting space is where your site data is going to be. These are two closely related, but individual services, even though many people believe that registering the domain name is enough. Much like the disk space and the monthly traffic features that a given web hosting plan provides, there are a certain number of registered domains that you can include as hosted i.e. you can have the web content for them in some account even when the domains have been registered through a different company. In technical terms, it doesn't matter whether a domain is registered and hosted with the exact same company or is registered with one company and directed to another - in either case your websites will operate the very same way.
