5. a1)Why do most programs use interrupt-driven I/) over busy-wait I/O? a2)When would you prefer to use busy-wait I/O over interrupt-driven I/O? b) Write ARM code that tests a register at location ds1 and continues execution only when the resister is non-zero. c) Draw a UML sequence diagram for copying characters from an input to an output device using interrupt-driven I/O. The diagram should include the two devices and the two I/O handlers.
