Computer Science / Unit 6 CS 0306 short lesson, about 20 seconds
The Three Process States
Captions available
The idea
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.
In practice
A class holds students working, hands raised, and one waiting on the printer.
Where people slip
Blocked is waiting on the world, not on the CPU.
