If you want to create a website, you need 2 things - a domain name and a web hosting plan for it. The domain registration is the actual web address that you type in an Internet browser to reach a website, while the hosting space is where your site data will be. These are 2 closely related, yet individual services, while many people think that registering the domain name is enough. Very similar to the disk space and the monthly traffic features that a given web hosting plan features, there are a certain number of registered domains that you can include 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 company. In technical terms, it doesn't matter whether a domain is registered and hosted with the exact same company or is registered with one company and directed to another - either way your sites will function in exactly the same way.
