Framework For A 2 Seater Buggy What Is The Difference Between A CMS And A Framework?

What is the difference between a CMS and a Framework? - framework for a 2 seater buggy

I read about Joomla and Drupal and described it as a CMS. Sometimes a frame, but does not appear to be the same as other frameworks such as Rails and Zend. Can someone explain the difference between the two? Who is right for Drupal and Joomla?
