Consider a disk that rotates at 3600 rpm. The seek time to move the head between

adjacent tracks are 2ms. There are 32 sectors per track, which are stored in linear order from sector 0 through sector 31. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8. There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the data from the buffer to the target track. [6.0 Marks]

How long will it take to transfer sector 1 on track 8 to sector 1 on track 9?
How long will it take to transfer all the sectors of track 8 to the corresponding sectors of track 9?

Consider a 4-drive, 200GB-per-drive RAID array. What is the available data storage capacity

for each of the RAID levels 0, 1, 3, 4, 5, and 6?

A user program starts execution at t=0sec, a scanner interrupt is call at t=16 sec during interrupt handling another camera interrupt has been call at t=21 sec and returns at t=35 sec, at a same time another printer interrupt is call and return at=43sec to scanner interrupt handler. Scanner interrupt returns at t=53 sec. Calculate the total time required to process interrupt.
