ABIs cover details such as 

• data type, size, and alignment; 
• the calling convention, which controls how functions‘ arguments are passed and return values retrieved; 
• the system call numbers and how an application should make system calls to the operating system;

ABIs may be defined at the processor-architecture level or at the OS level. the ABIs are standards to be followed by the code-generator phase of the compiler. the standard is fixed either by the OS or by the processor.

functionality: define the mechanism/standard to make function calls independent of the implementation language or a specific compiler/linker/toolchain. provide the mechanism which allows JNI, or python-c interface etc
