Round Robin (RR) scheduling algorithm is mainly designed for time-sharing systems. This algorithm is similar to FCFS scheduling, but in Round Robin (RR) scheduling, preemption is added which enables the system to switch between processes. A fixed time is allotted to each process, called a quantum, for execution.
