Mathematical Formula
Overview & Explanation
CPU Job Scheduling determines which process in the ready queue is allocated the CPU.
How It Works
- Track process arrival times and burst times.
- Execute processes according to FCFS or Round Robin policy.
- Compute turnaround and waiting metrics.
Practical Applications
- OS kernel thread scheduling analysis
- Performance modeling
FCFS Scheduling Example
Processes P1(0, 4), P2(1, 3)
P1 Exec
t=0..4
