In order to make a website, you need two things - your own domain and a 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 two tightly related, but separate services, even though many people assume that registering the domain is enough. Very similar to the disk space and the monthly traffic features which a given web hosting plan features, there are a certain number of registered domains which you can include 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 firm. In technical terms, it doesn't matter if a domain is registered and hosted with the same company or is registered with one company and directed to a different one - either way your sites will operate the very same way.
