If you wish to make a web site, you need two things - a domain and a hosting plan for it. The domain registration is the actual web address that you type in a web browser to reach a website, while the hosting space is where your website files is going to be. These are two tightly related, but individual services, although many people believe that registering the domain name is enough. Much like the disk space and the monthly traffic features that a given web hosting plan features, there are a certain number of registered domains which you can add as hosted i.e. you can have the web content for them in some account even when the domains have been registered via a different firm. 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 directed to another - either way your websites will operate in exactly the same way.
