Techopedia explains DirectX
DirectX serves as the bridge between the underlying hardware and development platform and helps developers access the underlying hardware's audio and visual capabilities through pre-developed APIs. DirectX is mainly used to develop video games and multimedia applications that require enhanced interaction and automation from system hardware.
DirectX also may be used to access input/output (I/O) functions but is popularly used to create and manage graphical application components. Application creation requires the DirectX Development Kit (DDK).
