Question

Quizplus · Accepted Answer

The API (Application Programming Interface) provides a set of functions and procedures that allow a program to access the hardware and services provided by the operating system or other software. It is often used in conjunction with a high-level programming language and can be considered a layer between the application and the operating system. JCL (Job Control Language) is used to control batch processing on mainframe computers, ISA (Instruction Set Architecture) is a low-level programming language used to program microprocessors, and ABI (Application Binary Interface) is a specification for how functions and data are organized in a compiled program.
