A Control Panel is a web-based user interface through which you can control various aspects of your web presence. For instance, you could create or modify site files, set up and check e-mails, control databases, check visitor statistics etc. These things are done using buttons and menus within a web browser and the CP could also be called ‘back office’, i.e. the admin area associated with your web hosting account. Most Control Panels available will allow you to handle all hosting-related matters, but you'll commonly need a different system to manage payments or to get a new domain name when the company offers domain registrations. Based on the platform they utilize, you may 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 use a 3rd system.
