If you wish to create a web site, you need two things - your own domain name and a web hosting plan for it. The domain registration is the actual web address which you enter in an Internet browser to access a site, while the hosting space is where your site files is going to be. These are two tightly related, yet individual services, even though many people believe that registering the domain name is enough. Very similar to the disk space and the monthly traffic features which a given hosting plan provides, there are a certain number of registered domain names that you can add as hosted i.e. you can have the web content for them in some account even when the domains have been registered via a different company. In technical terms, it doesn't matter if a domain is registered and hosted with the exact same company or is registered with one company and pointed to another - in any case your websites will function in exactly the same way.
