What research have you done on your own? What do you know about them so far? Definitions are not hard to find.

structures allocate separate memory for all the fields specified
unions allocate memory equal to the largest datatype specified and all the fields reference the same space.
enums are just aliases for integers that are more organized and convenient than using #DEFINE
