The Master Page acts like a template for all pages that use it. All those
pages inherit the structure and code of the Master Page an add on top of
that the customization for each page. That way you can have the Web site
header and footer, style, structure, etc. applied to all pages.
On the other side the Web User Control is an element that can be placed on
any page to provide repeatable functionality with no need to implement on
each page. An example is a menu control that can be place on each page where
the menu is needed.
