If you wish to create a web site, you need two things - a domain and a hosting plan for it. The domain registration is the actual website address which you enter in a web browser to reach a site, while the hosting space is where your website data will be. These are 2 very closely related, yet separate services, although many people believe that registering the domain is enough. Much like the disk space and the monthly traffic features which a given web hosting plan offers, there are a certain number of registered domains you can include as hosted which means that you can have the web content for them in some account even when the domains are actually registered through a different company. In technical terms, it does not matter whether a domain is registered and hosted using the same company or is registered with one company and pointed to a different one - in any case your websites will function exactly the same way.
