A Control Panel is a web-based interface where you can handle numerous aspects of your world-wide web presence. For example, you can set up or change website files, set up and check emails, manage databases, check visitor stats and so forth. Those things are executed via buttons and menus inside a browser and the CP may also be called ‘back office’, i.e. the administrative area associated with your web hosting account. Most of the Control Panels available on the market will permit you to control all hosting-related matters, but you'll commonly need a different system to manage payments or to get a new domain in case the company offers domain registrations. Depending on the platform they use, you can be able to use the billing account to open a support ticket to ask a question or to diagnose an issue as well, or you might have to use a 3rd system.
