In order to create a website, you need two things - a domain name and a website hosting plan for it. The domain registration is the actual website address which you type in a browser to access a website, while the hosting space is where your website files is going to be. These are two very closely related, but separate services, even though many people assume that registering the domain name is enough. Very similar to the disk space and the monthly traffic features which a given hosting plan provides, there are a certain number of registered domain names which 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 if 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 exactly the same way.
