Comparison Between FCFS and RR Scheduling
The Key Difference between First Come First Served (FCFS) and Round Robin (RR) Scheduling is that First Come First Served is the Non-Preemptive scheduling Whereas, Round Robin is the Preemptive scheduling.

Comparison Chart
First Come First Served (FCFS) | Round Robin (RR) |
---|---|
FCFS is the non-preemptive scheduling algorithm. | RR is the preemptive scheduling algorithm. |
It has minimum overhead | It has a low overhead |
Response time high | Good Response time for a short process. |
Inconvenient for the time-sharing system | Convenient for the time-sharing system |
The workload is processed in the order of arrival | Similar to FCFS but uses time quantum. |
No Starvation | No Starvation |
