In order 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 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 closely connected, but individual services, while many people think that registering the domain is enough. Much like the disk space and the monthly traffic features that a given web hosting plan has, there are a certain number of registered domain names you can add as hosted i.e. you can have the web content for them in some account even when the domains are actually registered through a different firm. In technical terms, it does not matter whether a domain name is registered and hosted with the exact same company or is registered with one company and pointed to another - either way your websites will function exactly the same way.
