In Simplest Manner :

Delegate : A Delegate is a reference pointer to a method. It allows us to treat method as a variable and pass method as a variable for a callback. When it get called , it notifies all methods that reference the delegate.

Events : Events adds a layer of abstraction and protection on delegate, this protection prevents client of the delegate from resetting the delegate and invocation list.

there is very good tutorial on this Unitygeek.com
