An Application Binary Interface (ABI) defines the low-level interface between two binary program modules, ensuring that compiled code can run on a given system without modification. It specifies details such as data types, calling conventions, and how functions are accessed in machine code, which are crucial for cross-language interoperability and system compatibility.

Data types are fundamental attributes that define the kind of data that can be stored and manipulated within a programming environment, influencing how operations are performed on the data. They ensure efficient memory usage and prevent operations on incompatible data, thus maintaining data integrity and program reliability.
