A Control Panel is a web-based user interface using which you can control various aspects of your presence online. As an example, you can easily set up or modify website files, create and check emails, control databases, check visitor stats and so on. Those things are performed using buttons and menus within a web browser and the Control Panel can also be called ‘back office’, i.e. the administrative area associated with your web hosting account. Most of the Control Panels out there will allow you to handle all hosting-related matters, but you shall normally require a different system to control payments or to get a new domain when the company offers domain registrations. Based on the platform they utilize, you could be able to use the billing account to open a support ticket to ask a question or to resolve a problem also, or you may need to employ a 3rd system.
