Executes tasks in the order of being added 10 of 12 What does the shortest job first algorithm do? Organizes the queue according to size and then executes accordingly 11 of 12 What does the shortest remaining time algorithm do? Executes whichever task has the shortest time left for executing, also allowing added processes to take over the currently running process 12 of 12
