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