Question

interrupts are normally arranged for what​

Answer 1

Answer:

Data transfer between the CPU and the peripherals is initiated by the CPU. But the CPU cannot start the transfer unless the peripheral is ready to communicate with the CPU. When a device is ready to communicate with the CPU, it generates an interrupt signal. A number of input-output devices are attached to the computer and each device is able to generate an interrupt request.

The main job of the interrupt system is to identify the source of the interrupt. There is also a possibility that several devices will request simultaneously for CPU communication. Then, the interrupt system has to decide which device is to be serviced first.
