In computer science and computer programming, a data type (or simply type) is a classification identifying one of various types of data.

Data type determines:

Data types are used within type systems, which offer various ways of defining, implementing and using data types.

Different type systems ensure varying degrees of type safety.

Almost all programming languages explicitly include the notion of data type, though different languages may use different terminology.

Common data types include:
