When an interrupt occurs, the operating system first saves the context of the currently running process, including the program counter and other registers. It then determines the cause of the interrupt and executes the appropriate interrupt handler to address it. After processing the interrupt, the OS restores the saved context of the interrupted process and resumes its execution, ensuring a seamless continuation of tasks. This mechanism allows the OS to respond promptly to external events or internal conditions while maintaining system stability.

Is operating system interrupt driven?
Yes, an operating system is interrupt driven.
What is an interrupt operating system and how does it handle interruptions in the execution of tasks?
An interrupt operating system is a type of operating system that can pause the execution of tasks to handle unexpected events or requests. When an interruption occurs, the operating system temporarily stops the current task, saves its state, and then processes the interrupt. Once the interrupt is handled, the operating system resumes the original task from where it left off. This allows the system to efficiently manage multiple tasks and respond to external events in a timely manner.
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.
What are the differences between a trap and an 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.

What page fault in operating system?
a page fault is a hardware or software interrupt,it occurs when an access to a page that has not been brought into main memory takes place.
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...
How ISR is serviced?
when interrupt occurs, the program counter content will stores into stack, an PC will load interrupt address for next instruction execution. ofter completion ISR process PC will retrieves the stack values and execution will be continued.
Traditional IBM mainframes recognize different interrupt types?
Yes, from first versions of the IBM 360 architecture there are different interrupt types that put the system into Supervisor mode and invoke the operating system to analyze the interrupt type
What is trap in operating system?
software generated interrupt caused either by an error or a user request.
When an operating system receives an interrupt from the printer and pauses the CPU it is performing what?
This is called processor management.
How does OS handle interrupt?
The operating system (OS) handles interrupts by using an interrupt handling mechanism that includes interrupt detection, prioritization, and servicing. When an interrupt occurs, the CPU pauses its current execution, saves the state of the running process, and transfers control to a specific interrupt handler routine associated with the interrupt. The handler processes the interrupt, which may involve reading input from devices or handling errors, and then restores the saved state of the interrupted process before resuming its execution. This efficient management allows the OS to respond promptly to hardware events while maintaining system stability and performance.
