If you wish to make a website, you need 2 things - your own domain and a website hosting plan for it. The domain registration is the actual website address which you type in an Internet browser to access a website, while the hosting space is where your site files is going to be. These are two tightly connected, but separate services, even though many people think that registering the domain is enough. Very similar to the disk space and the monthly traffic features that a given hosting plan provides, there are a certain number of registered domains that 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 using a different firm. 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 pointed to a different one - in any case your websites will function in exactly the same way.
