IRQ stands for Interrupt ReQuest. It allows other hardware in your computer to interrupt what the CPU is doing, because there is something else that needs to be done. For example, when you press a key on your key board, an IRQ is generated that says a key has been pressed. If there were no IRQs, then the CPU would have to check the keyboard over and over again to see if a key has been pressed, which wastes time.
Interrupt Request
IRQ 3.
LTP1 should use IRQ7.
IRQ 1 is used exclusively for the keyboard controller.
None. Its the graphics card that uses an IRQ. The monitor is just a peripheral.

IRQ 3
An interrupt request, or IRQ
Depends if it's sharable or not. You could try moving the card to another slot.
Interrupt Requests are method for handling requests from components such as Keyboard, Mouse, Clock etc & get attention of Processor.Each specific components is assigned IRQ number.
IRQ 0 - System timer. IRQ 1 - Keyboard. IRQ 2 - Cascaded signals from IRQs 8-15. IRQ 3 - COM2 (Default) and COM4 (User) serial ports IRQ 4 - COM1 (Default) and COM3 (User) serial ports IRQ 5 - LPT2 Parallel Port 2 or sound card IRQ 6 - Floppy disk controller IRQ 7 - LPT1 Parallel Port 1 or sound card (8-bit Sound Blaster and compatibles) IRQ 8 - Real time clock IRQ 9 - Free / Open interrupt / Available / SCSI. Any devices configured to use IRQ 2 will actually be using IRQ 9. IRQ 10 - Free IRQ 11 - Free IRQ 12 - PS/2 connector Mouse. IRQ 13 - ISA / Math Co-Processor IRQ 14 - Primary IDE. If no Primary IDE this can be changed IRQ 15 - Secondary IDE These are just a set of standard IRQs. For much more detail check our Ralf Brown's list located at http://www.cs.cmu.edu/~ralf/files.html
By default, the IRQ for the floppy disk controller is IRQ 6.
