Primary disadvantage of programmed I/O is that CPU spends most of its time in a tight loop waiting for the device to become ready. This is called busy waiting. With interrupt-driven I/O, the CPU starts the device and tells it to generate an interrupt when it is finished. Done by setting interrupt-enable bit in status register. cell phone clip holder for ring light
