Which concept represents a pre-defined set of characteristics that specify the type of value a variable has, such as a string or integer?

• A. Data Type
• B. Input Screen Design
• C. Variables
• D. Source Document

Answer: (C)

Data type defines the kind of value a variable can hold and the operations that apply to it, such as string for text or integer for whole numbers. It sets the characteristics of the data, including what values are valid, how much memory is needed, and which operations are meaningful. The variable itself is just the storage location for that value, while the data type describes the nature of the data stored in it. So the concept described is data type.
