In order to make a web site, you need 2 things - a domain name and a website hosting plan for it. The domain registration is the actual website address which you type in a web browser to access a website, while the hosting space is where your site files will be. These are two very closely related, yet separate services, while many people think that registering the domain name is enough. Very similar to the disk space and the monthly traffic features which a given website hosting plan offers, there are a certain number of registered domains you can include as hosted i.e. you can have the web content for them in some account even when 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 using the same company or is registered with one company and pointed to a different one - in either case your websites will function the very same way.
