If you want to make a website, you need 2 things - your own domain and a hosting plan for it. The domain registration is the actual website address that you enter in a browser to access a website, while the hosting space is where your website files will be. These are 2 very closely related, yet independent services, even though many people believe that registering the domain is enough. Much like the disk space and the monthly traffic features which a given website hosting plan has, there are a certain number of registered domain names which you can include as hosted which means that you can have the web content for them in some account even when the domains are actually registered through a different provider. In technical terms, it doesn't matter whether 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 sites will function the very same way.
