If you want to create 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 an Internet browser to reach a website, while the hosting space is where your website files is going to be. These are 2 very closely related, but separate services, while many people think that registering the domain name is enough. Much like the disk space and the monthly traffic features which a given web hosting plan provides, there are a certain number of registered domain names that you can include as hosted which means that you can have the web content for them in some account even if the domains are in fact registered via a different company. In technical terms, it does not matter whether a domain is registered and hosted with the same company or is registered with one company and pointed to another one - in either case your websites will function exactly the same way.
