A Set is a collection that has no duplicate elements.  
A List is a collection that has an order assoicated with its elements.  
A map is a way of storing key/value pairs. The way of storing a Map is similar to two-column table.

Adding couple of other differences between Set and Map:
1. You can have an iterator for a set but not a map.
2. Processing a complete map takes longer whereas processing a complete set takes a comparatively less time (reason - iterator)
