If you want to create a web site, you need two things - your own domain and a website hosting plan for it. The domain registration is the actual website address that you enter in a web browser to access a site, while the hosting space is where your website files will be. These are two tightly related, yet individual services, while many people think that registering the domain name is enough. Much like the disk space and the monthly traffic features which a given hosting plan has, there are a certain number of registered domains you can add as hosted which means that you can have the web content for them in some account even if the domains are in fact registered via a different service provider. In technical terms, it doesn't matter if a domain is registered and hosted with the same company or is registered with one company and pointed to another - in any case your sites will operate exactly the same way.
