Explain Scheduling Point of a Task Scheduling Algorithm?

The scheduling point of a scheduler are the points on the time line at which he scheduler makes decisions regarding which task is to be run next.

How Scheduling Points are Determined in Clock Driven, Event Driven and Hybrid Schedulers?

Clock Driven

In a clock driven scheduler, the scheduling points are defined at the time instants marked by interrupts generated by a periodic timer.

Event Driven

The scheduling points in an event driven scheduler are generated by occurrence of certain events.

Hybrid Schedulers

For hybrid schedulers, the scheduling points are defined both through the clock interrupts and event occurrences.
