If you wish to create a website, you need 2 things - your own domain name and a website hosting plan for it. The domain registration is the actual website address that you enter in a browser to access a site, while the hosting space is where your site files will be. These are two tightly related, but independent services, while many people believe that registering the domain name is enough. Similar to the disk space and the monthly traffic features which a given web hosting plan provides, there are a certain number of registered domains that you can add 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 service provider. In technical terms, it does not matter whether a domain is registered and hosted with the exact same company or is registered with one company and pointed to another one - in any case your websites will function exactly the same way.
