Document Summary

Itec1000-a assignment #3: the goal of scalar processing is to produce on average, the execution of one instruction per clock tick. 10^9): if there were no interrupts provided in a computer particularly with respect to events external to the cpu, then the consequences would be that the cpu would have to find out any events that have happened. On the other hand, hard disks also have to spin up, but the disks are permanently integrated into the computer. They aren t disks which can be inserted or removed, they are locked into the system that reads them, so they spin up much faster: formula for average latency time= 1/2 x 1/rational speed. Rational speed to revolution per second: 7200 rev/min x [1 min/60 sec] = 120 rev/second. Average latency time= 1/2 x 1/120 rev/second = 0. 004167 seconds = 4. 167 milliseconds: transfer time = 1/ number of sectors x rational speed.
