In order to make a web site, you need two things - a domain and a website hosting plan for it. The domain registration is the actual website address that you type in a browser to access a site, while the hosting space is where your site data is going to be. These are 2 very closely connected, but independent services, although many people believe that registering the domain name is enough. Just like the disk space and the monthly traffic features which a given hosting plan provides, there are a certain number of registered domain names you can include as hosted i.e. you can have the web content for them in some account even when the domains are actually registered through a different firm. In technical terms, it does not matter if a domain name is registered and hosted with 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.
