In order to create a website, 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 browser to access a website, while the hosting space is where your website data is going to be. These are 2 closely related, but separate services, although many people think that registering the domain is enough. Just like the disk space and the monthly traffic features that a given hosting plan features, there are a certain number of registered domains you can add as hosted which means that you can have the web content for them in some account even if the domains are in fact registered using a different provider. In technical terms, it does not matter whether a domain name is registered and hosted using the same company or is registered with one company and pointed to another - either way your sites will function the very same way.
