What is an interface?

An interface is the set of methods, messages, or VIs (think connector panes) that we use to pass data in and out of a software module. Simply put, what are the inputs and outputs, and how do they get in and out? A software module could be a class, a library, or simply a repository of VIs (in descending order of author preference).

Why are interfaces useful?
