A Control Panel is a software tool that is used to control the content of a web hosting account. Including, but is not limited to, files, e-mails, databases, statistics along with other operations executed with them. The CP offers a web-based interface to manage all of these things and everything else related to the hosting service using different sections in which you can access functions through buttons and/or menus. The simpler to use a CP is, the simpler it'll be for you to control your presence online in its entirety. In the common scenario, the CP is the hosting account’s back office, while a different billing account is employed to manage payments and domain registrations - if the company offers this particular service. Trouble tickets could be managed via the billing account or by using a different system.
