checkpoints

Checkpoints are saved moments during a process, like a computer’s task or a game, that allow the work to be resumed from that point if interrupted. Think of them as markers or bookmarks—if something goes wrong, instead of starting over, you can restart from the most recent checkpoint. In computing, checkpoints help manage large or complex tasks efficiently, ensuring progress is preserved and reducing the loss of work. They enable smoother, safer operation, especially in long or critical processes such as training machine learning models or performing system updates.
