If you wish to create a website, you need 2 things - a domain name and a website hosting plan for it. The domain registration is the actual website address which you type in an Internet browser to reach a site, while the hosting space is where your website data will be. These are 2 tightly related, but individual services, although many people assume that registering the domain is enough. Very similar to the disk space and the monthly traffic features that a given hosting plan features, there are a certain number of registered domain names you can include as hosted i.e. you can have the web content for them in some account even if the domains are in fact registered through a different provider. In technical terms, it doesn't matter whether a domain name is registered and hosted using the same company or is registered with one company and directed to another one - in either case your websites will operate exactly the same way.
