Variables are storage for values. They are identified by a name.
Values are a pair of:
1) a representation (numbers stored in computer memory)
2) a meaning associated with that representation (also called a type).
Example (C programming language):
char c = 'A';
c is a variable (a location in computer memory, identified by the name c)
c stores the value 'A', which is:
the number 65, meaning the index of character A in the ASCII table.
