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
