okay i figured it out..
Collection-----
if we wish to represent group of individual object as a single entity.

Maps----
if we want to store both value and the key (key, value pair) then we use mapping concept.

map works on key whereas collection works on index
basically map is used when we dont want duplicate objects (as keys are unique)
