If you want to create a website, you need 2 things - a domain name and a website hosting plan for it. The domain registration is the actual web address which you type in a browser to access a website, while the hosting space is where your website data is going to be. These are 2 very closely related, yet individual services, while many people believe that registering the domain is enough. Just like the disk space and the monthly traffic features which a given web hosting plan provides, there are a certain number of registered domain names which you can add as hosted which means that you can have the web content for them in some account even if the domains have been registered using a different company. In technical terms, it doesn't matter if a domain is registered and hosted using the same company or is registered with one company and directed to another - in either case your sites will operate in exactly the same way.
