If you wish to create a website, you need two things - a domain and a web hosting plan for it. The domain registration is the actual website address which you type in an Internet browser to access a website, while the hosting space is where your site files will be. These are 2 very closely related, but individual services, even though many people think that registering the domain name is enough. Just like the disk space and the monthly traffic features that a given website hosting plan provides, there are a certain number of registered domain names you can include as hosted which means that 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 is registered and hosted with the same company or is registered with one company and directed to another one - in any case your sites will operate in exactly the same way.
