3. Polling Consider a system that uses polling to control to its 4 disk drives. Assume that a poll takes 100 nanoseconds to accomplish and that the requirement is that CPU reacts within 10 microseconds of the disk being ready. What percentage of the CPU is required to manage the disk drives?
What is the average time to read or write a 512-byte sector for a typical disk rotating at 45,000 RPM? The advertised average seek time is 2 ms, the transfer rate is 400 MB/sec, and the controller overhead is 0.2 ms. Assume that the disk is idle so that there is no waiting time.
Suppose that a magnetic disk has an average seek time of 4 ms, a rotation rate of 5400 RPM, a transfer rate of 50 MB/second, a sector size of 512 bytes, and controller overhead of 2 ms. What is the average amount of time to read a single sector?

A CPU with interrupt-driven I/O is busy servicing a disk request. While the CPU is midway through the disk-service routine, another I/O interrupt occurs.Q.) What happens next?
The data transfer can be handled by various modes. some of the modes use CPU as an intermediate path, others transfer the data directly to and from the memory unit and this can be handled by 3 following ways: Programmed I/O, Interrupt-Initiated I/O and Direct Memory Access (DMA) Identify/define the data transfer processes involved in each method.
Calculate the access time for a disk having the size of 512 byte/sector and the seek time of 12ms. The rotational rate is 5700 RPM. The data transfer rate is 3MB/sec, and the the controller overhead is 1ms, you may even assume that there is no service time for the access.
