Study Notes
CPU Scheduling and Gantt Chart
- Three processes (P1, P2, P3) arrive at time zero with burst times of 24, 3, and 3 milliseconds respectively.
- The First-Come-First-Served (FCFS) scheduling algorithm is used.
Process Details
- Process P1: burst time of 24 milliseconds
- Process P2: burst time of 3 milliseconds
- Process P3: burst time of 3 milliseconds
Performance Metrics
- Average Waiting Time (AWT): (6 + 0 + 3) / 3 = 3 milliseconds
- Average Turnaround Time (ATT): ((30 - 0) + (3 - 0) + (6 - 0)) / 3 milliseconds
- Average Response Time (ART): (6 + 0 + 3) / 3 = 3 milliseconds
