the difference between a subset and a proper subset
A subset of a set S can be S itself. A proper subset cannot.
Proper subset definitionA proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in Abut A contains at least one element that is not in B.For example, if A={1,3,5} then B={1,5} is a proper subset of A. The set C={1,3,5} is a subset of A, but it is not a proper subset of A since C=A. The set D={1,4} is not even a subset of A, since 4 is not an element of A.

No.ASCII stands for American Standard Code for Information Interchange. It couldn't be called a standard if it varied from machine to machine.Note that this only applies to the core ASCII values. Some machines/programs/formats will use a subset or extended set of ASCII codes.

Because every set is a subset of itself. A proper subset cannot, however, be a proper subset of itself.

No. The null set cannot have a proper subset. For any other set, the null set will be a proper subset. There will also be other proper subsets.
