If you want to create a web site, you need two things - a domain name and a web hosting plan for it. The domain registration is the actual web 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 2 closely connected, yet separate services, while many people think that registering the domain name is enough. Much like the disk space and the monthly traffic features that a given website hosting plan features, there are a certain number of registered domains that you can add as hosted i.e. you can have the web content for them in some account even if the domains are actually registered using a different firm. In technical terms, it does not matter whether a domain name is registered and hosted with the same company or is registered with one company and pointed to a different one - in either case your websites will operate exactly the same way.
