In order to create a web site, you need two things - a domain and a website hosting plan for it. The domain registration is the actual web address which you enter in an Internet browser to reach a website, while the hosting space is where your site files will be. These are two tightly connected, but separate services, even though many people assume that registering the domain is enough. Just like the disk space and the monthly traffic features which a given web hosting plan has, there are a certain number of registered domain names you can add as hosted i.e. you can have the web content for them in some account even when the domains are actually registered through a different service provider. In technical terms, it does not matter whether a domain name is registered and hosted with the exact same company or is registered with one company and pointed to another one - in either case your sites will function the very same way.
