2 votes 2 votes As SJF is based on shortest Burst time and we cannot predict burst time before execution it makes the whole SJF impractical abhay nanda answered Sep 2, 2017 abhay nanda comment Share Follow See all 2 Comments See all 2 2 Comments reply suvasish pal commented Sep 2, 2017 reply Follow Share then all scheduling depend upon burst time.is not it? 0 votes 0 votes abhay nanda commented Sep 5, 2017 reply Follow Share Yes all of them depends upon burst time. But majority of them of are not practically possible as you dont know burst time before hand. For that some prediction methods to predict burst time and then scheduling algorithms can be applied. Also there is no accurate prediction method as of now so this makes all of the scheduling algorithm more or less practically impossible to be implemented ACCURATELY. 0 votes 0 votes Please log in or register to add a comment.
