A scheduling algorithm in which processes are activated in a fixed cyclic order. Those which cannot proceed because they are waiting for some event (e.g. termination of a child process or an input/output operation) simply return control to the scheduler. The virtue of round-robin scheduling is its simplicity - only the processes themselves need to know what they are waiting for or how to tell if it has happened. However, if a process goes back to sleep just before the event for which it is waiting occurs then the event will not get handled until all the other processes have been activated.
