If you want to make a web site, you need two things - a domain name and a website hosting plan for it. The domain registration is the actual web address which you type in a browser to access a site, while the hosting space is where your website files is going to be. These are 2 very closely connected, yet separate services, although many people think that registering the domain name is enough. Similar to the disk space and the monthly traffic features that a given website hosting plan offers, there are a certain number of registered domains which you can add as hosted which means that you can have the web content for them in some account even when the domains are actually registered via a different provider. In technical terms, it does not matter if a domain is registered and hosted with the same company or is registered with one company and pointed to another - in either case your websites will operate in exactly the same way.
