Consider a system that uses interrupt-driven I/O for a particular device which has an average data transfer rate of 10 KBps. The processing of the interrupt which includes the time to jump to ISR, its execution and returning to the main program is 250 µs. The fraction of processor time of consume by I/O device, if I/O device interrupts for every 2 byte (in %) is
