A Control Panel is a web-based interface using which you can manage different aspects of your presence online. For example, you can easily create or edit site files, set up and check emails, handle databases, check visitor statistics and so on. These things are done using buttons and menus in a web browser and the Control Panel may also be called ‘back office’, i.e. the admin area associated with your web hosting account. Most Control Panels out there will enable you to control all hosting-related matters, but you shall normally require a different system to take care of payments or to get a new domain 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 and fix a problem also, or you might have to employ a 3rd system.
