cPanel is an easy-to-use control panel designed for managing particular domains, or hosting accounts, on your dedicated or virtual dedicated server. End users can control everything from adding/removing email accounts to administering MySQL databases.
cPanel is used in conjunction with WebHost Manager, or WHM. WHM provides administrative control of your dedicated or virtual dedicated server. You use WebHost Manager to create individual accounts, add domains to your server, manage hosting features, and performing basic system and control panel maintenance.
