The Three Process States
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A process cycles through execution states: ready when awaiting a core, running when executing, blocked when awaiting an event such as input — transitions driven by scheduler and events.
Show
A class holds students working, hands raised, and one waiting on the printer.
Watch for
Blocked is waiting on the world, not on the CPU.
