When multiple interrupts from different devices appear at about the same time, a priority scheme could be used to determine the order in which the interrupts would be serviced. Discuss what issues need to be considered in assigning priorities to different interrupts.

and Explanation:

Variety of factors that determine the priority scheme and interrupts the device through enabling the device to code used to handle system to generated by the user through priority here.

Second Interrupts control the device and interrupts to perform the task by copy data and always delayed.

The third device has real-time constraints on where data is handled over the device.

The device does not have some buffering and is preferred that available only for a short duration. A priority scheme work and allow to subset of the priorities with projects and use to achieve the goals. Restrict the available priorities and control the order. Select the default priority and assign the created issues in the project.
