When an interrupt handler finishes, how does the CPU resume execution wherever it was before the
interrupt was triggered?
Step by step
Solved in 2 steps
- The CPU incurs one or more _________________ when it’s idle, pending the completion of an operation by another device in the computer system.When an interrupt occurs, the CPU suspends the current process to handle it. It's called interrupt service. Why is the present procedure being suspended? Why can't we simply finish the present task and deal with the interruption later?When an interrupt is received, the CPU immediately suspends the current process and begins responding to the interrupt. Is there a good reason to stop a running process? Because finishing the process of executing it and dealing with interrupts are mutually exclusive.
- whenever an interrupt is triggered, the CPU stops what it is doing and then gets back to work on servicing the next process Is it necessary to postpone the execution? Instead, how about just executing the procedure and taking care of the remainder?When a CPU interrupt is received, the process is terminated and the CPU handles the new one.Why should the procedure not be halted? Why can't we just finish the execution and cleanup?When the CPU receives a signal, it stops whatever it is doing to deal with the incoming request. The mechanism operates as follows: Spooling with B as the interrupt signal C as the interrupt handler D as the polling mechanism.
- Whenever the CPU receives a signal, it stops whatever it is doing to deal with the incoming request. So, here's how the mechanism operates: Spooling with B as the interrupt signal C as the interrupt handler D as the polling method A'.When a signal is received, the CPU suspends its current activity to process the request. The technique used in this instance is: A' Signal of Interrupt Spooling B C' Interrupt Handling D Polling.When an interrupt arrives, the CPU suspends the currently operating process to deal with it. This is referred to as interrupt service. What is the rationale for stopping the present process? As an alternative, why can't we simply finish the present procedure and deal with the interruption later?
- When an operation is stopped and accepted by the CPU, it goes on to the next job, a CPU interrupt is sent. Why can't the process be halted if it's already running? The execution and cleanup can wait till we've resolved the problem, so why not start now?When a signal is received, the CPU suspends its current activity to respond to the request. Here's how the mechanism works: A' Signal to interrupt Spooling with B C' Handling of interrupts D Polling.The CPU suspends its present operation upon receiving a signal in order to reply to the request. How the mechanism operates: A' Interrupt signal Spooling with B' Interrupt handling C' Polling
