DirectX is a collection of APIs for handling tasks related to multimedia, especially 3D graphics and game programming and video, on Microsoft platforms.

Microsoft DirectX is a collection of APIs for handling tasks related to multimedia, especially 3D graphics and game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with Direct, such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. The name DirectX was coined as shorthand term for all of these APIs (the X standing in for the particular API names) and soon became the name of the collection.
