Chapter 11: MANAGING DEVICE DRIVERS   4 DEVICE DRIVER FUNCTIONS A device driver exposes device-specific routines  to device-independent functions in the operating  system. A device driver allows you to manipulate the  physical properties of hardware devices. A device driver can provide functionality through  two separate driver components—a high-level  driver and a low-level driver.

Chapter 11: MANAGING DEVICE DRIVERS   5 DEVICES AND DRIVERS Some drivers (standard keyboard, mouse) are  generic, so a single driver can be used with  hundreds of compatible devices. Other drivers are very specific and work only with  a specific model of device. Generic drivers require less frequent updating  and therefore present fewer challenges to the  administrator.
