Data Type
PronunciationDAY-tuh TYPE
Definition
A data type is an attribute that tells a computer system how to interpret the value of data, such as whether it is a number, text, or a boolean. It determines the operations that can be performed on the data and how it is stored in memory.
Where you hear it
During code reviews, when defining variables, or when reading documentation for a programming language.
Examples
The variable stores an integer data type.
You must ensure the function receives the correct data type.
Common mistake
Confusing the data type with the actual value itself, or assuming that all languages handle data types in the same way (e.g., static vs. dynamic typing).
