Round Robin Scheduling Calculator for CPU Processes

Visualize the Round Robin CPU Scheduling Algorithm

Round Robin (RR) is a preemptive scheduling algorithm used by operating systems to manage how processes are assigned time on the CPU. It's designed to give each process a fair share of CPU time, preventing any single process from monopolizing the system.

How It Works:

Processes are placed in a queue. Each process is allowed to run for a short, fixed amount of time called a "time quantum".

If a process finishes before its time quantum expires, it releases the CPU, and the next process in the queue begins.

If a process does not finish within its time quantum, it is interrupted (preempted) and moved to the back of the queue, and the CPU is given to the next process.

Using the Simulator:

Enter your processes with their arrival times and burst times (the total CPU time they need). Set a time quantum. The calculator will simulate the entire scheduling process, showing you a Gantt chart of the execution order and calculating key performance metrics like average waiting time and average turnaround time.
