Round-robin scheduling

Round-robin scheduling is a scheduling discipline for processes in an operating system, which assigns time slices, "time quanta", to each process in equal portions and order, without any priorities between the processes. All processes will thus have the same priority.

In prioritized scheduling systems, processes on an equal priority are often adressed in a round-robin manner.

The word comes from the round-robin principle known from other fields, where each person takes equal share of something.
