First, restating the question and options helps frame what we’re evaluating.
Question: In programming, what is a variable?
Answer options:
- It is a go-between for programming code and machine language.
- It is the actual data that is stored by the computer.
- It is a type of information that is stored on the computer.
- It is a name given to a specific storage area in the Random Access Memory (RAM).

Now, let’s analyze each option individually.
Option 1: 'It is a go-between for programming code and machine language.' This description sounds like an interpreter, compiler, or translator role in some contexts, or possibly a conceptual bridge, but it doesn’t define a variable. It misplaces the variable’s core function, which is not to translate code but to hold data.
Option 2: 'It is the actual data that is stored by the computer.' This describes data itself, not the mechanism used to refer to or manage it. A variable is a named container for data, not the data value itself. So this option confuses the container with its contents.
Option 3: 'It is a type of information that is stored on the computer.' This is vague and broad; it could refer to data types or files in general. A variable is not simply a type of information; it’s a named storage location that can hold data of a certain type during program execution.
Option 4: 'It is a name given to a specific storage area in the Random Access Memory (RAM).' This captures the essential idea: a variable is a symbolic name that references a particular memory location where a value can be stored and retrieved during the program’s run. It emphasizes the naming and the storage area aspect, which aligns with standard programming definitions.

In summary, Option 1 misidentifies the role of a variable, Option 2 confuses the data with the container, Option 3 is too broad and imprecise, and Option 4 precisely describes a variable as a named storage area in RAM that holds a value for a program to use.
