Q 1. Suppose we have a 1.5-GHz CPU to which the following three I/O devices are connected:
Polling requires 300 instructions for each I/O device. Students are required to compute the percentage of CPU time required to poll each device.
Q 2. Instead of polling, we want to use interrupts for handling the DVD drive. Keeping in view the DVD drive to be active only 12% of the time, you are required to compute the percentage of CPU time for handling it.
Note: Interrupt and polling requires the same amount of instructions.
