Algorithm Reference

FCFS

Processes run in order of arrival. Simple, no starvation, but can cause convoy effect.

SJF (Non-Preemptive)

Picks the shortest job from ready queue. Optimal average waiting time but can starve long jobs.

SRTF (Preemptive SJF)

Preempts current process if a shorter one arrives. Best average waiting time, most context switches.

Round Robin

Each process gets a fixed time quantum. Fair, good response time, quantum affects performance.

Priority

Lower number = higher priority. Non-preemptive. Can cause starvation of low-priority processes.

Formulas

Turnaround = Completion − Arrival

Waiting = Turnaround − Burst
