In order to make a website, you need 2 things - a domain name and a web hosting plan for it. The domain registration is the actual website address which you enter in a web browser to reach a website, while the hosting space is where your website data will be. These are 2 tightly connected, but individual services, while many people think that registering the domain is enough. Similar to the disk space and the monthly traffic features which a given web hosting plan provides, there are a certain number of registered domain names which you can include as hosted which means that you can have the web content for them in some account even when the domains are in fact registered using a different company. In technical terms, it does not matter if a domain is registered and hosted with the exact 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.
