The internal nuclear current drive (KS) model supports multimedia devices such as sound cards, TV capture cards, this chapter introduces usually core-core concepts
1.1 Overview of the core concept
Multimedia devices can support a group of various technologies, in order to support these devices for a wider range, Microsoft introduces the kernel stream (KS) drive model.
