If you wish to create 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 access a site, while the hosting space is where your site files is going to be. These are two tightly connected, but independent services, while many people assume that registering the domain is enough. Similar to the disk space and the monthly traffic features which a given website 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 service provider. In technical terms, it does not matter if 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 function the very same way.
