Checkpointing

Checkpointing is a process used in computing where a system saves its current state at a specific point in time. This allows the system to recover or restart from that point if needed, such as after a crash or failure, rather than starting over from scratch. Think of it like saving your progress in a video game—so if you lose connection or experience an error, you can resume from your last save instead of beginning again. This technique helps improve reliability and efficiency, especially in long or complex computations.
