What is round-robin scheduling?

Question

In a multitasking operating system context, sometimes you hear the term round-robin scheduling. What does it refer to?
What other kind of scheduling is there?

Answer 1

Round robin is a simple scheduling algorithm where time is divided evenly among jobs without priority.

For example - if you have 5 processes running - each process will be allowed to run for 1/5 a unit of time before another process is allowed to run. Round robin is typically easy to implement in an OS.
