Interrupt Request. A line or signal which is activated by a peripheral to issue a hardware interrupt to the CPU.
Interrupt ReQuest. A set of 16 lines on the PC Bus, that when asserted by the I/O device, notifies the CPU that the device is in need of servicing. IRQ's 2 and 9 are ganged, as this is the way that the PC architecture was extended from the 8 bit 8 IRQ 'PC/XT' bus to the 16 bit 286 'AT' bus.

Interrupt request line- Each device connected to a computer (microprocessor) must have a specified interrupt line value. With Plug-and Play (PnP), users do not need to set IRQ values manually (or be aware of them) when adding a new device to a computer. BIOS specifies IRQ routing tables for them.

An IRQ is a signal from a piece of hardware (such as a keyboard or sound card) indicating that it needs the CPU to do something. The interrupt request signals run along the IRQ lines to an interrupt controller that assigns priorities to incoming IRQs and delivers them to the CPU.Found on http://www.majorgeeks.com/glossary.php?id=9
Interrupt Request level. In IBM-PCs, a setting given to peripheral devices like soundcards and CD-ROM drives that identifies them to the computer's CPU. When the peripheral needs to communicate with the CPU, it will send an interrupt with that value. Problems will result if two or more peripherals are set to the same IRQ value.Found on http://www.encyclo.co.uk/local/22285
