The best way to understand the difference between WHM and cPanel is that WHM is for people who administer the servers (System Administrators) and Resellers whereas cPanel is for the End Users (i.e. clients).
WHM and cPanel can be considered in the following three-level hierarchy:
Full WHM – Complete administrative control over the server
Reseller WHM – Restricted level of administrative control over the server
cPanel – Client level of admin rights restricted to features to manage their individual account(s) as specified by the Server Administrator or Reseller

The features and quotas available to a cPanel user are set by either a System Administrator or a Reseller via the WHM Interface. Therefore cPanel users have access to a limited range of the server’s functions and are only in control of their own domains.
The main features that they can access are summarised as follows:
cPanel File Management
Users can manage their files and the disk space allocated to them. They can also manage key functions such as FTP for uploading files, managing backups and password protecting directories.
cPanel Database Management
In this area end, users can manage their MySQL databases using PHPMyAdmin which is a graphical tool for managing databases.
cPanel Domain Management
Here customers can manage their domains with useful features such as using addon domains to host more than one website, set up domain redirection or create subdomains (to host eg: a blog).
cPanel Email Features
cPanel offers full email management so that end users can add, remove and edit email accounts, create autoresponders, set up email forwarding and many other features to ensure they can manage their email service in exactly the way they want it to operate.
