What is cPanel/WHM?

WHM enables you quick, easy and automated management of your sever and to very easily create web hosting packages, and it provides your users access to a powerful cPanel control panel for the purpose of managing individual accounts within WHM. The cPanel server itself is divided into two parts:

• the WHM server control panel (root access to WHM)
  The server administrator has access and complete control over all WHM functions. They can access all WHM interface levels, including WHM resellers and the cPanel end user interface. There is only one administrator user on the server.
• cPanel control panel for the hosting end user
  cPanel is a control panel used for direct management of individual hosting accounts.
  The options available to the user depend on administrator settings, or reseller settings if the end user is their client.
