Yes.
It is the set of all elements we are considering or dealing with in a given problem. We use a capital U or sometimes capital E to mean the universal set. Now take ANY two sets, A and B. If every single element of set A is contained in set B, we say A is a subset of B. The empty set is a subset of every set. Every set in contained in the universal set, so they are all subset of it.
If I understand the question correctly then a is a proper subset of u.
There are 250 subsets. That is 1,125,899,906,842,624 of them and I am NOT proposing to list them.
the difference between a subset and a proper subset
The universal subset is the empty set. It is a subset of all sets.
0 is subset of 0 no doubt. subset means taking part of universal set.here you are taking whole part of universal set.so 0 is subset of 0.
Yes. A null set is always a subset of any set. Also, any set is a subset of the [relevant] universal set.

the difference between a subset and a proper subset
Since ASCII ⊊ unicode, I don't know if there are ASCII codes for subset and proper subset. There are Unicode characters for subset and proper subset though: Subset: ⊂, ⊂, ⊂ Subset (or equal): ⊆, ⊆, ⊆ Proper subset: ⊊, ⊊,
Because every set is a subset of itself. A proper subset cannot, however, be a proper subset of itself.
A is a subset of a set B if every element of A is also an element of B.
