Application Binary Interface (ABI)

An Application Binary Interface (ABI) is a set of rules that define how software programs communicate with the operating system and hardware at a low level. It specifies details like how data is organized in memory, how functions are called, and how different software components interact. Think of it as a contract ensuring that compiled programs and system libraries work together correctly, regardless of who developed them. This standardization allows programs to run smoothly across different systems and facilitates compatibility between compiled code and hardware components.
