What does IRQ mean in FILE EXTENSIONS
IRQ is an acronym for Interrupt Request, also known as IRQ line or IRQ number. It is a signal sent by an input hardware device, like keyboard, mouse, or printer, to the Central Processing Unit (CPU) or computer processor in order to communicate something; for example, that it is ready to send or receive data. The CPU receives and processes the interrupt request and then acts on it accordingly. Each device connected to your computer's motherboard has its own unique interrupt request line or number assigned to it which is used as an address so the CPU can determine what type of action needs to be taken when the signal is received

Essential Questions and Answers on I R q in "COMPUTING»FILEEXT"
What are IRQs?
Interrupt request lines (IRQs) are an essential component of computer architecture that allow peripherals and other devices to communicate with the processor. An interrupt request line signals the processor to temporarily pause its regular activities and take care of a higher-priority task from a device connected to it. This helps ensure that input and output operations can be handled efficiently, even if they occur simultaneously.
How many IRQs are available?
It depends on the computer system but typically, most computers support at least 8-16 IRQs, allowing for multiple devices or peripherals to connect easily. Computers, especially high performing ones, may have additional dedicated IRQs for better performance.
What is the purpose of using IRQ?
The main purpose of using an interrupt request line is to ensure that time-sensitive tasks in a computer are handled efficiently and quickly. An interrupt request line allows for devices or peripherals to send signals directly to the processor so it can prioritize them and process them before its other tasks.
What kind of tasks require an IRQ?
Typical tasks that require interrupts include time-critical operations such as reading input from keyboards or mice, playing music or videos, handling printer requests, responding to network traffic, etc. Simply put, these types of tasks need immediate attention otherwise data could be lost or misinterpreted.
How do I know what Devices have been assigned which IRQ?
You can typically view which devices have been assigned which interrupts by going into your computer's System Information toolbox (usually located in Control Panel). Alternatively you can use device manager in Windows operating systems to determine this information as well.
Can two or more devices share an IRQ?
Yes it is possible for two or more devices to share an interrupt line if both devices do not require immediate attention continuously . In this way , they can share the same resources within their operations without interfering with one another.
Is there any danger in changing my computer’s IRQ assignments?
If you make a mistake when setting up your assignment then yes there could potentially be some dangerous consequences. For instance if two different components try using the same interrupt then this could lead to conflicts between those components causing them not to work properly or even crash your system completely.
What should I do if I run out of available IRQ’s?
If you run out of available interrupts then you will need to find a way of consolidating some components together so they can share interrupts without causing instability issues. One option would be rewriting device drivers so that they support SHARED INTERRUPTS functionality - however this requires quite a bit technical knowledge and expertise..
