Shortest Job Next

Shortest Job Next (SJN) is a scheduling method used by computers to decide which task to run next. It prioritizes the task with the shortest estimated execution time remaining, aiming to reduce wait times and improve overall efficiency. By selecting the quickest tasks first, SJN minimizes idle periods and can improve system responsiveness, especially when tasks vary widely in their processing times. However, it requires accurate knowledge of each task's duration and can potentially delay longer tasks, leading to possible fairness concerns. Overall, it seeks to optimize how a computer manages multiple tasks for better performance.
