Note:
IRQ (Interrupt Request) lines are system resources allocated to
I/O devices. When an I/O device needs to gain attention of the oper-
ating system, it signals this by causing an IRQ to occur. After receiv-
ing the signal, when the operating system is ready, the system will
interrupt itself and perform the service required by the IO device.
