Microsoft DirectX is a group of technologies designed to make Windows-based computers an ideal platform for running and displaying applications rich in multimedia elements such as full-color graphics, video, 3D animation, and rich audio. It includes security and performance updates, along with many new features across all technologies, which can be accessed by applications using the DirectX APIs.
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 a shorthand term for all of these APIs (the X standing in for the particular API names) and soon became the name of the collection.
DirectX introduces significant improvements across its suite of APIs. DirectSound offers new audio capabilities, DirectShow accelerates video rendering hardware, and Direct3D enhances low-level graphics programmability with new programmable vertex and pixel shader 2.0 models.
