An Application programming interface (API) is a source code
interface that an operating system or library provides to
support requests for services to be made of it by computer
programs. Advanced programming interface is a near synonym
with wider application that predates the current common
usage. In the original term the concept is meant to
represent any well defined interface between two separate
programs. The main difference is that this older term does
not inculcate a parent-child relationship and can therefore
be applied to peer-to-peer situations more logically, e.g.
internal kernel services which can present themselves as
separate programs.
