In a computer, a vectored interrupt is an I/O interrupt that tells the part of the computer that handles I/O interrupts at the hardware level that a request for attention from an I/O device has been received and also identifies the device that sent the request.
A vectored interrupt is an alternative to a polled interrupt , which requires that the interrupt handler poll or send a signal to each device in turn in order to find out which one sent the interrupt request.

What is the difference between polling and vectored interrupt system with example?
i need compare between vectored interrupt system and polling
What is the purpose of interrupts in Operating System?
Answer: An interrupt is a hardware-generated change-of-flow within the system. An interrupt handler is summoned to deal with the cause of the interrupt; control is then returned to the interrupted context and instruction. A trap is a software-generated interrupt. An interrupt can be used to signal the completion of an I/O to obviate the need for device polling. A trap can be used to call operating system routines or to catch arithmetic errors.Type your answer here...
What is the difference between software and hardware interrupt?
The difference is that a hardware interrupt is a signal relayed to a system's CPU directly because of some piece of hardware, such as a keyboard or mouse. A software interrupt is a signal sent to indicate that something within a piece of software requires attention.
Is operating system interrupt driven?
Yes, an operating system is interrupt driven.

What is the purpose of trap in operating system?
The purpose of a steam trap is discharging noncondensable and condensable gases. They are essentially automatic valves that discharge using a small amount of live steam.

What does polling frequency mean?
Polling frequency refers to how often a system or device checks for new information or updates. A higher polling frequency means it checks more frequently, while a lower frequency means it checks less often. Adjusting the polling frequency can impact performance and efficiency of the system.
What is the difference between trap and interrupt?
Trap is actually a software generated interrupt caused either by an error (for example division by zero, invalid memory access etc.), or by an specific request by an operating system service generated by a user program. Trap is sometimes called Exception. The hardware or software can generate these interrupts. When the interrupt or trap occurs, the hardware therefore, transfer control to the operating system which first preserves the current state of the system by saving the current CPU registers contents and program counter's value. after this, the focus shifts to the determination of which type of interrupt has occured. For each type of interrupt, separate segmants of code in the operating system determine what action should be taken and thus the system keeps on functioning by executing coputational instruction, I/O instruction, torage instruction etc.
When an operating system receives an interrupt from the printer and pauses the CPU?
Processor management is the operating system that receives and interrupt from the printer and pauses the CPU.
