The means by which an entity interacts with something. In programming, an interface is often used to provide abstraction of functions. The interface defines what methods that a function or class MUST possess. This allows the simple replacement of functions with any other function which also meets the requirments, without requiring any modification elsewhere in the program (particular useful when porting to a different platform, or using an alternate rendering system, etc).
