title: Keyboard interrupts
body: <p>I am studying low-level device driver stuff. I am confused between interrupts and IRQ. A sample driver code that hooks keyboard suggests keyboard interrupt is 0x31 but my book on microprocessor says it is 0x09. On opening 'Device Manager->Keyboards->Resources', it shows IRQ is 1. Can anyone clarify this?</p>
  
  <p>Thanks,
