In order to make a web site, you need two things - your own domain name and a web hosting plan for it. The domain registration is the actual web address that you enter in a web browser to access a website, while the hosting space is where your site data is going to be. These are two tightly connected, yet individual services, while many people think that registering the domain is enough. Similar to the disk space and the monthly traffic features that a given web hosting plan offers, there are a certain number of registered domain names which 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 via a different firm. In technical terms, it doesn't matter whether a domain name is registered and hosted using the same company or is registered with one company and pointed to a different one - in either case your sites will operate in exactly the same way.
