A Control Panel is a tool used to control the content of a hosting account. Including, but is not limited to, files, emails, databases, stats along with other operations carried out with them. The CP provides a web-based interface to handle all of these things and everything else associated with the Internet hosting service using different sections in which you can access functions through menus and/or buttons. The simpler to use a CP is, the simpler it'll be for you to manage your presence online altogether. In the common case, the Control Panel is the hosting account’s back office, while an independent billing account is used to handle payments and domain registrations - if the company offers that service. Trouble tickets can be handled from the billing account or through a different system.
