Universal set.
Once example is the whole numbers and subsets are the numbers 1,2 and 3 written {1,2,3}. Another example is all the colors. Subsets would be any number of individual colors. The universal set may be finite or infinite.
It is the set of "everything".
If the universal set, U, has N elements then it has 2N subsets.
The null set. It is a subset of every set.

"Universe" and "universal set" are two unrelated concepts.
A universal set is a set that contains all the elements under consideration for a particular discussion or problem. It is used in set theory to define the range of possibilities within a given context.
If the universal set contains N elements then it has 2N subsets.
Yes. A null set is always a subset of any set. Also, any set is a subset of the [relevant] universal set.
The universal set is the set containing each and every element under consideration.
It is the set of "everything".
If the universal set, U, has N elements then it has 2N subsets.
The complement of an empty set is universal set
The null set. It is a subset of every set.
