If you want to create a web site, you need 2 things - a domain name and a website hosting plan for it. The domain registration is the actual web address that you type in an Internet browser to reach a website, while the hosting space is where your website files is going to be. These are two very closely connected, but separate services, even though many people assume that registering the domain is enough. Much like 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 add as hosted which means that you can have the web content for them in some account even when the domains are in fact registered through a different firm. In technical terms, it doesn't matter if a domain name is registered and hosted with the same company or is registered with one company and pointed to a different one - in any case your websites will function in exactly the same way.
