If you want to make a web site, you need two things - your own domain name and a hosting plan for it. The domain registration is the actual web address which you enter in a browser to reach a site, while the hosting space is where your site files will be. These are two closely connected, but separate services, while many people believe that registering the domain is enough. Very similar to the disk space and the monthly traffic features which a given website hosting plan has, there are a certain number of registered domains you can include 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 service provider. In technical terms, it does not matter whether a domain is registered and hosted with the same company or is registered with one company and directed to another - in any case your sites will operate the very same way.
