In order to create a website, you need two things - a domain name and a website hosting plan for it. The domain registration is the actual website address which you type in a web browser to reach a website, while the hosting space is where your site files is going to be. These are two very closely connected, yet separate services, while many people think that registering the domain is enough. Similar to the disk space and the monthly traffic features which a given hosting plan provides, there are a certain number of registered domains that you can include as hosted i.e. you can have the web content for them in some account even if the domains have been registered via a different service provider. In technical terms, it does not matter if a domain 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 function the very same way.
