What Is The Difference Between Sets And Logic's?

A set is a collection of objects. It is hard to tell what you are referring to with the term "logic's", so the difference cannot be described.

Similar symbols are used for set operations of "intersection" and "union" and for logic operations of "and" and "or" (respectively). The set operators work on collections of objects. The logic operators work on Boolean variables and constants (true, false). Because the operations are so different, there is usually no confusion as to the meaning of the symbol in a given context.
