Drivers are hardware-dependent and operating-system-specific. The higher-level code can be written independently of whatever specific hardware device it may control. Because drivers require low-level access to hardware functions in order to operate, drivers typically operate in a highly privileged environment and can cause system operational issues if something goes wrong. In addition, the bus support subsystem provides interfaces that allow drivers to perform bus-specific tasks. 15.4Device Driver Subsystem The device driver subsystem contains all of the driver-specific code. https://www.coursehero.com/file/p1m8v60/Drivers-are-hardware-dependent-and-operating-system-specific-They-usually/
