Process scheduling algorithm based on time slice.A time quanta is given to each process for its execution. as the time slice is expired,the other process is allowed to execute.
Round robin (RR) is one of the simplest scheduling algorithms for processes in an operating system. As the term is generally used, time slices are assigned to each process in equal portions and in circular order, handling all processes without priority (also known as cyclic executive). If a process hasn't finished by the end of the time slice, it is moved to the back of the queue so the next process in line can have its turn. Round-robin scheduling is simple, easy to implement, and starvation-free. Round-robin scheduling can also be applied to other scheduling problems, such as data packet scheduling in computer networks.
The name of the algorithm comes from the round-robin principle known from other fields, where each person takes an equal share of something in turn
