11. Often the device drivers may need more flexibility than the module interface affords. 12. In MINIX 3, each device driver is a separate user-mode process. 13. In modern terminology, VTAM provides a communication stack and device drivers . 14. Full specifications will be published and open source device drivers will be released. 15. The Linux kernel is a monolithic kernel, hence device drivers are kernel components. 16. Also, NT is incompatible with many common software programs and hardware device drivers . 17. Device drivers may then relay information to a running program by various means.18. This interface is normally done by a Device Driver or Hardware Abstraction Layer. 19. Device drivers are also libraries, but they implement a standardized interface.20. Gamepads typically require device drivers if used on contemporary personal computers.
