If you wish to create a web site, you need 2 things - a domain name and a website hosting plan for it. The domain registration is the actual web address which you type in a web browser to reach a website, while the hosting space is where your website files is going to be. These are two closely connected, but independent services, even though many people think that registering the domain name is enough. Much like the disk space and the monthly traffic features which a given web hosting plan has, there are a certain number of registered domain names that you can add as hosted which means that you can have the web content for them in some account even if the domains are actually registered via a different company. In technical terms, it does not matter if a domain is registered and hosted using the same company or is registered with one company and directed to a different one - either way your websites will operate exactly the same way.
