Answer / veveritoiulpofticios
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.

A variable is like a named "box" that holds a value. the name of the "box" is the variable name. Where a variable is used, it's actually the value held in the "box" that is used.
