If you want to make a web site, you need two things - a domain name and a web hosting plan for it. The domain registration is the actual web address that you enter in a browser to reach a site, while the hosting space is where your website data will be. These are 2 closely related, yet separate services, while many people believe 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 domains which 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 through a different service provider. In technical terms, it does not matter whether a domain name is registered and hosted with the same company or is registered with one company and pointed to another - in any case your sites will operate in exactly the same way.
