The easiest way to think of a complement of a set is what's left over after you take out the given set.
For example, if you have the set of all children that attend your local elementary school. Then the complement of all the boys that attend the elementary school would be all the girls that attend the elementary school.

the set of every set is that set
null set or empty set, is a set with no elements.
The set contained in another set is termed as a sub-set.
A null set is a set that does not contain any elements, an empty set.
