Solution

In computer system ,an interrupt request or (IRS) is a hardware signal sent to the processor that temporarily stops arunning program and allows a special program to run.

Interrupt lines are often identified by an index with the format ITQ followed by a number. There are eight interrupt inputs commonly reffered to as IRQ0 to IRQ7.

IRQ(Interrupt request) 7 shows port 1.It is used for printers or for any parallel port if a printer is not present, it can also be potentially shared with a secondary sound card with careful management of the port.

For IRQ 7 equivalent hex code is 0F h.
