1. AIM: To write a C program to simulate the shortest job first algorithm with preemption. DESCRIPTION: For implementing SJF algorithm with preemption‚ we consider the arrival times of each process‚ the burst times of all the previously arrived processes. After the arrival of all the processes into the ready queue‚ the average waiting time and turn around time can be calculated by using the above algorithm. ALGORITHM: 1) start 2) read the no of processes to n 3) initialize i to 0 4) if

services did the system provide that gave UP a competitive advantage? Up was among the first to acquire Big Iron. The railroad used the mainframe to roll out one of the earliest transaction processing systems. UP was also the first railroad to develop a computerized car-scheduling system. Because it could efficiently schedule railroad car pickups and deliveries‚ the scheduling system gave UP a competitive advantage. 2. Why does UP feel that now if the time to replace its Big Iron system? UP was one
