If you want to create a website, you need 2 things - your own domain name and a 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, although many people think that registering the domain name is enough. Very similar to the disk space and the monthly traffic features that a given hosting plan has, there are a certain number of registered domains that you can include 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 if a domain name is registered and hosted with the exact same company or is registered with one company and pointed to another one - either way your websites will function exactly the same way.
