If you wish to make a web site, you need two things - your own domain and a website hosting plan for it. The domain registration is the actual web address that you enter in a browser to access a site, while the hosting space is where your website files is going to be. These are two very closely related, yet independent services, even though many people think that registering the domain is enough. Just like the disk space and the monthly traffic features that a given hosting plan provides, there are a certain number of registered domain names that you can add as hosted which means that you can have the web content for them in some account even if the domains have been registered using a different company. In technical terms, it does not matter whether a domain name is registered and hosted with the same company or is registered with one company and directed to a different one - either way your websites will operate exactly the same way.
