device driver
     
         {Software} to control a hardware component
        or {peripheral} device of a computer such as a {magnetic
        disk}, {magnetic tape} or printer.
     
        A device driver is responsible for accessing the hardware
        {register}s of the device and often includes an {interrupt
        handler} to service interrupts generated by the device.
     
        Device drivers often form part of the lowest level of the
        {operating system} {kernel}, with which they are linked when
        the kernel is built.  Some more recent systems have loadable
        device drivers which can be installed from files after the
        {operating system} is running.
