If you want to make a web site, you need 2 things - a domain and a website hosting plan for it. The domain registration is the actual web address that you enter in a browser to reach a website, while the hosting space is where your website data is going to be. These are two very closely related, but individual services, although many people think that registering the domain is enough. Similar to the disk space and the monthly traffic features that a given web hosting plan provides, there are a certain number of registered domain names you can add as hosted which means that you can have the web content for them in some account even if the domains are actually registered using a different service provider. In technical terms, it doesn't matter whether a domain is registered and hosted with the same company or is registered with one company and directed to a different one - in either case your websites will function in exactly the same way.
