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 web address which you enter in a web browser to access a website, while the hosting space is where your website files will be. These are two closely connected, yet individual services, although many people assume that registering the domain name is enough. Very similar to the disk space and the monthly traffic features which a given web hosting plan features, there are a certain number of registered domain names that you can include as hosted i.e. you can have the web content for them in some account even when the domains are in fact registered through a different company. In technical terms, it does not matter whether a domain name is registered and hosted with the exact same company or is registered with one company and pointed to a different one - in any case your websites will function exactly the same way.
