What is the difference between a variable and an identifier?

A variable is a memory location given a name and a data type. Once a variable has been declared its contents may be modified using its name.
An identifier is the name you give a variable. (In the case of Visual Basic and most other languages this needs to start with a letter and can contain numbers or underscores).
