      Well! Exceptions are software interrupts which are synchronous while HW interrupts are asynchronous and caused by hardware devices connected to machine. Both types of interrupts are taken care by their respective interrupt handlers, the top halves. In either case, to service interrupts, execution switches from user space to kernel space.
