Clock-driven (time-driven) schedulers
- Scheduling decisions are made at specific time instants, which
are typically chosen a priori.
• Priority-driven schedulers
- Scheduling decisions are made when particular events in the
system occur, e.g.
• a job becomes available
• processor becomes idle
- Work-conserving: processor is busy whenever there is work to
be done.
They are turned by a gear train, which in turn is driven by a spring-driven, weight-driven, or electric motor. Their direction of rotation is normally clockwise when viewing the clock's "face".

Test Driven Development
They are turned by a gear train, which in turn is driven by a spring-driven, weight-driven, or electric motor. Their direction of rotation is normally clockwise when viewing the clock's "face".
A spring-driven clock uses a tightly wound spring to store potential energy. As the spring unwinds, the energy is transferred to gears, which regulate the movement of the clock hands. The escapement mechanism, controlled by the gear train, ensures that the clock hands move in precise increments.
If it's a cable driven, use a crank and place it in the keyhole and turn it. If it's chain driven, same way you'd wind a cuckoo clock, pull the end with the ring to raise the weight to the base of the clock.
A weight driven clock uses a hanging weight to provide the energy needed to power the clock mechanism. As the weight descends, it turns gears that regulate the movement of the clock hands. The weight needs to be wound up periodically to keep the clock running.

The gear-driven clock was said to have been invented by the German locksmith Peter Henlein around 1510. He is often credited with creating the first portable clock, known as a "Nuremberg egg," which was a small, spring-powered device.
