It is usually a rectangular boundary of a Venn diagram. It is the area surrounding all the circular shapes in these diagrams.
Universal set.
A set is a collection of distinct objects, while a universal set is the set that contains all possible elements relevant to a particular discussion or context. Every set is a subset of the universal set, meaning that all elements of a set are also elements of the universal set. The concept of a universal set helps define boundaries for discussions involving sets, ensuring clarity about which elements are included or excluded.
The complement of a set refers to the elements that are not included in that set but are part of a larger universal set. For example, if the universal set is all natural numbers and set A consists of even numbers, the complement of set A would be all the odd numbers within the universal set. Mathematically, the complement of set A is often denoted as A'.
If the universal set, U, has N elements then it has 2N subsets.
It is the set of "everything".
Universal set.
"Universe" and "universal set" are two unrelated concepts.
The universal set is the set of all possible elements under consideration. You can have a universal set of all people, or all bird species, or all numbers or whatever. You can even have a universal set of all people and all bird species and all numbers as one big set.
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.
