Task scheduling is an important concept in Design and Analysis of Algorithms and operating systems because it helps in reducing the waiting time, turnaround time, and overall execution time of jobs in a system. To minimize the total amount of time spent in the system, the Shortest Job First (SJF) scheduling algorithm is commonly used. In this algorithm, the process having the minimum service time is executed first. Since shorter tasks finish quickly, the average waiting time and turnaround time are minimized. The given jobs and their service times are: Job 1 → Service Time = 3 Job 5 → Service Time = 7 Job 2 → Service Time = 4 Job 10 → Service Time = 8 According to the SJF scheduling algorithm, the jobs are arranged in ascending order of their service times. Therefore, the execution order becomes: Job 1 → Job 2 → Job 5 → Job 10 because: 3 < 4 < 7 < 8 Now the scheduling calculations are performed. For Job 1: Waiting Time = 0 Turnaround Time = 0 + 3 =
