data type
This term is a technical specification used primarily in computer science and software engineering. It defines the nature of data, such as whether a value is a whole number, a decimal, or a string of characters, which in turn dictates how the computer's memory allocates space and which logical operations are permissible.
In professional documentation, it is often used interchangeably with "type" in the context of type systems. While "data" is often treated as an uncountable mass noun in general English, "data type" functions as a standard countable noun because there are distinct, individual categories of types (e.g., integer, boolean, float) within any given programming language.
