About this video
CORRECTION: At 4.40 I compared process time(20,30,10) but here we will compare the total CPU Burst time only to select the shortest job.
CPU Burst Time for P1 = 10(excluding IO time),
P2 = 15,
P3 = 5.
So we compare (10,15,5) and allocates the CPU to P3 as it is having shortest Burst Time.
Discussed the Shortest Job First(Non-Preemptive) CPU Scheduling Algorithm with processes containing CPU time and IO time.
