CPU Scheduling Calculator – FCFS, SJF, Round Robin Explained
A CPU Scheduling Calculator helps students and developers calculate waiting time and turnaround time for different scheduling algorithms like FCFS, SJF, and Round Robin.
⚙️ What is CPU Scheduling?
CPU scheduling is a process used by operating systems to decide which process will use the CPU next. It improves efficiency and system performance.
📊 FCFS (First Come First Serve)
FCFS executes processes in the order they arrive. It is simple but may cause long waiting times.
📐 Formula
Waiting Time = Previous Burst Time + Previous Waiting Time
Turnaround Time = Burst Time + Waiting Time
📊 Example
| Process | Burst Time | Waiting Time | Turnaround Time |
|---|---|---|---|
| P1 | 5 | 0 | 5 |
| P2 | 3 | 5 | 8 |
