API - Application Program(ming) Interface

(A-P-I)

Any set of routines generally available for use by programmers. The operating system, for example, has APIs for a variety of disk/file handling tasks. APIs are written to provide portable code. The programmer only has to worry about the call and its parameters and not the details of implementation, which may vary from system to system.
