What is irq3 used for?
IRQ Interrupt Request 3 are usually reserved for COM port (1,2,3,4) but can be assigned to anything.Interrupts are a commonly used technique for computer multitasking, especially in real-time computing. Such a system is said to be interrupt-driven.An act of interrupting is referred to as an interrupt request (IRQ
What is the full form of IRQ and its function?
Interrupt Request
What type of computer resources are direct lines to the processor and used by computer componets to request attention from the CPU?
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.
What does IRQ stand for?
Abbreviation of interrupt request line, and pronounced I-R-Q. IRQs are hardware lines over which devices can send interrupt signals to the microprocessor. When you add a new device to a PC, you sometimes need to set its IRQ number by setting a DIP switch. This specifies which interrupt line the device may use. IRQ conflicts used to be a common problem when adding expansion boards, but the Plug-and-Play specification has removed this headache in most cases.see: http://www.webopedia.com/TERM/I/IRQ.html
When a computer device is in need of immediate attention it sends the OS?
An interrupt request, or IRQ
What IRQ does LPT1 usually use?
LTP1 should use IRQ7.
What thing indicate a hardware conflict?
Received when two devices were trying to use the same interrupt request (or IRQ) to signal an interrupt to the Programmable Interrupt Controller (PIC).
What is irq3?
Interrupt Request - IRQ0 through IRQ7 commonly.Interrupts are a commonly used technique for computer multitasking, especially in real-time computing. Such a system is said to be interrupt-driven.An act of interrupting is referred to as an interrupt request (IRQ)
What is irq use for computer?
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.
What is the interrupt request number for the serial port 2?
IRQ 3 is for COM2 and COM4 (serial ports). See related link.
When a device needs the CPU to perform a task what does it need to do?
The device needs to signal the CPU to get its attention. It typically does this through an interrupt request line (IRQ).
What is IRQ 5?
This interrupt is the first choice that most sound cards make when looking for an IRQ setting.
