In order to create a web site, you need 2 things - your own domain name and a website hosting plan for it. The domain registration is the actual website address which you enter in an Internet browser to access a website, while the hosting space is where your site files is going to be. These are two very closely connected, 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 which you can include as hosted i.e. 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 doesn't matter if a domain is registered and hosted using the same company or is registered with one company and directed to another - either way your websites will function in exactly the same way.
