In answer to Geoffrey'
s question:

a set is a container than may contain only one instance of any value on the container's domain; a bag may contain more than one instance.

for example, consider a set of integers, versus a bag of integers. a bag might contain the items {1, 1, 1, 3, 7, 7, 9, 50, 100, 100}; a set may not have 
duplicate entries.
