Round-robin scheduling algorithm is one of the simplest scheduling algorithms. It is designed especially for time-sharing systems. The ready queue is treated as a circular queue. The algorithm assigns a time slice(also called time quantum) to each process in the ready queue in order, handling all processes without priority. A maximum of one time slice is allocated at once. If the remaining request is less than a time slice, only the remaining request time is allocated. Round-robin scheduling is both simple and easy to implement. It is also starvation-free.
