2. Device management¶
Device management is the entry-point of system programming. Programs have to know which devices are available to communicate with the user (graphic cards, input devices, etc.) or with other machines (network cards, etc.).
In this chapter, we present the basic concepts and we show examples with simple virtual devices provided by Linux. In the next chapters, we build on these concepts and we show how to use specific device classes: display devices, input devices, etc.
