If you want to create a web site, you need 2 things - your own domain name and a web hosting plan for it. The domain registration is the actual website address that you enter in an Internet browser to reach a site, while the hosting space is where your website files will be. These are 2 very closely connected, but separate services, while many people think that registering the domain is enough. Very similar to the disk space and the monthly traffic features that a given web hosting plan has, there are a certain number of registered domain names that you can include as hosted i.e. you can have the web content for them in some account even if the domains have been registered via 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 - in any case your sites will operate in exactly the same way.
