A Control Panel is a web-based user interface using which you can handle various aspects of your world-wide web presence. For instance, you could create or change site files, create and check emails, control databases, check visitor statistics and so on. Those things are done via buttons and menus in a browser and the Control Panel can also be called ‘back office’, i.e. the administration area associated with your web hosting account. Most Control Panels available will permit you to handle all hosting-related matters, but you'll often need a different system to handle payments or to get a new domain name when the company offers domain registrations. Based on the platform they employ, you could be able to use the billing account to open a support ticket to ask a question or to troubleshoot an issue as well, or you might have to employ a 3rd system.
