If you want to make 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 browser to access a website, while the hosting space is where your website data will be. These are two tightly connected, but individual services, while many people believe that registering the domain name 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 that you can add as hosted i.e. you can have the web content for them in some account even if the domains are in fact registered through a different provider. In technical terms, it does not matter if a domain is registered and hosted with the same company or is registered with one company and pointed to another one - in either case your websites will operate exactly the same way.
