In order to make a web site, you need 2 things - your own domain and a website hosting plan for it. The domain registration is the actual web address that you enter in an Internet browser to access a site, while the hosting space is where your website data will be. These are two closely related, yet independent services, even though many people believe that registering the domain is enough. Much like the disk space and the monthly traffic features that a given hosting plan features, there are a certain number of registered domains which 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 through a different service provider. In technical terms, it doesn't matter whether a domain is registered and hosted using the same company or is registered with one company and directed to another - in either case your sites will function exactly the same way.
