A Control Panel is a web-based user interface where you can control various aspects of your presence online. As an illustration, you can set up or change website files, create and check emails, handle databases, check visitor statistics and so forth. These things are done via buttons and menus inside an internet browser and the CP could also be called ‘back office’, i.e. the administration area associated with your web hosting account. Most of the Control Panels out there will allow you to manage all hosting-related matters, but you'll normally require a different system to manage payments or to get a new domain when the company offers domain registrations. Depending on the platform they use, you could be able to use the billing account to open a support ticket to ask a question or to diagnose a problem too, or you might have to employ a 3rd system.
