exceptions-- interrupts, traps, failures, and terminationsA) Interrupt handling: Asynchronous means that a hardware interrupt is not caused by any instruction, but by an event of an external I/O device.b) Traps and system calls: System calls are encapsulated functions that are internally implemented by instruction Int N.The most important use of traps is to provide system calls. System calls run in kernel mode and can access stacks in the kernel.The parameters of the system call are passed thro
