Question

Observe the table (picture) and do the following: 

Draw a Gantt Chart for the following scheduling policies:

1.  First Come First Served (FCFS

2. Shortest Remaining Time First (SRTF - preemptive version of Shortest Job First) 

Convention: if two jobs have the same remaining time, choose job that arrived earlier first.

3.  Round Robin (RR) scheduling policy with a quantum size of 2 units. 

Conventions:

1. If a job finishes before the end of its quantum, finish that quantum and begin a new one immediately.

2. If a job finishes its quantum at the same time as a new job (i.e., a new CPU burst for a job) arrives, place the job that just finished its quantum ahead of the newly arriving job in the job queue.
