"IRQ" stands for "Interrupt Request." In computing and hardware architecture, an IRQ is a signal used by hardware devices to get the attention of the central processing unit (CPU) and request that it be interrupted or paused to handle a specific task or event.

When you add a new device to a PC, you sometimes need to set its strongIRQ/strong number by setting a DIP switch. This specifies which interrupt line the device may use.

Stands for "Interrupt Request." PCs use interrupt requests to manage various hardware operations. Devices such as sound cards, modems, and keyboards can all send interrupt requests to the processor. For example, when the modem needs to run a process, it sends an interrupt request to the CPU saying, "Hey, hold up, let me do my thing!" The CPU then interrupts its current job to let the modem run its process.
