If you want to create a web site, you need two things - your own domain and a web hosting plan for it. The domain registration is the actual website address which you enter in a browser to access a site, while the hosting space is where your website data is going to be. These are 2 closely related, yet individual services, while many people think that registering the domain name is enough. Very similar to the disk space and the monthly traffic features that a given web hosting plan has, 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 are actually registered via a different company. In technical terms, it does not matter if a domain name is registered and hosted using the same company or is registered with one company and pointed to another - in either case your sites will operate in exactly the same way.
