They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.Ī driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. Without a device driver, the particular hardware fails to work accordingly, which means it fails in doing a particular action for which it has been created.ĭrivers are hardware-dependent and operating-system-specific. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without knowing precise details about the hardware being used.ĭevice Drivers are important for a computer system to work properly. A device driver is a computer program that operates or controls a particular device attached to a computer or automaton. Operating System takes help from device drivers to handle all I/O devices.
