Best Answer

The interrupt of a proces or thread on the processor has been introduced to avoid a big proces/thread to consume too much of the processor power and therefore "starving" other processes.

Interruption is also used to stop crashed processes which are running an endless loop or are waiting for resources for too long.

By interrupting a process, the processor can continue with another process and pick up later with the big process when it has waited for his turn again and by this sheduling processes to run on the processor more efficiently.

An interrupt will be called after x time or x cycles, which depends from machine (computer) to machine (computer).

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 use of interrupt vector?

An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table. Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is generated, the processor saves its execution state via a context switch, and begins execution of the interrupt handler at the interrupt vector.

Where is interrupt handler and interrupt vector?

In the 8086/8088, the interrupt vector table is the first 1024 bytes of memory. In the 8085, the interrupt vector table is the first 64 bytes of memory if using the RST form of interrupt, otherwise the interrupt vector is provided by the interrupting device, usually in the form of a CALL instruction. The interrupt handler is wherever the interrupt vector points to.

What is vector and non vector interrupts?

VECTOR INTERRUPT If the interrupt is assigned to any predefined branching address to its ISR it is termed as vector interrupt. NON VECTOR INTERRUPT If the interrupt is not assigned to any predefined branching address to its ISR it is termed as non-vector interrupt. PRIYAKRISH


What is nested interrupt?

I believe a nested interrupt, is where an interrupt is allowed to occur (and thus is handled) during an already occurring Interupt service ruotine. I.E. First interrupt occurs ISR1 begins second Interrupt occurs ISR2 begins ISR2 Finishes ISR1 continues from where left off ISR1 finishes
