Question: 4. (10 points) A computer has a CPU that can execute 10 million instructions per second and memory has a transfer rate of 100 million
4. (10 points) A computer has a CPU that can execute 10 million instructions per second and memory has a transfer rate of 100 million bytes per second. When interrupt-driven I/O is performed, the ISR has to execute 50 instructions to transfer one byte between memory and I/O device. What is the maximum data transfer rate during I/O operations implemented by using interrupt-driven I/O?
