• A driver provides a software interface to hardware devices, enabling other software to access hardware functions without needing to know precise details about the hardware.
• A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects.
• When a calling program invokes a routine in the driver, the driver issues commands to the device.
