If you want to make a website, you need two things - your own domain and a website hosting plan for it. The domain registration is the actual website address that you enter in a web browser to access a site, while the hosting space is where your website files will be. These are two very closely connected, yet independent services, while many people believe that registering the domain is enough. Much like the disk space and the monthly traffic features that a given website hosting plan provides, there are a certain number of registered domain names which you can add as hosted which means that you can have the web content for them in some account even when the domains are actually registered via a different company. In technical terms, it doesn't matter if a domain is registered and hosted with the same company or is registered with one company and pointed to another - in either case your websites will function in exactly the same way.
