If you wish to create a web site, you need two things - a domain name and a web hosting plan for it. The domain registration is the actual website address that you type in an Internet browser to reach a site, while the hosting space is where your website data will be. These are 2 closely related, but separate 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 provides, 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 when the domains are in fact registered via a different company. In technical terms, it doesn't matter whether a domain name is registered and hosted using the same company or is registered with one company and directed to another one - in any case your websites will function the very same way.
