why shortest job first is special case of priority scheduling
Question
why shortest job first is special case of priority scheduling
Solution
Sure, here is the explanation:
-
Priority Scheduling is a method of scheduling processes that is based on priority. In this, the process with the highest priority is chosen for execution. And if two processes have the same priority then they are executed according to their sequence in the queue.
-
Shortest Job First (SJF) is a scheduling algorithm in which the process with the smallest execution time is chosen for execution next.
-
SJF can be considered as a special case of priority scheduling because in SJF, we can consider the priority of a process as the inverse of its burst time. The shorter the burst time, the higher the priority and vice versa.
-
Therefore, if we assign each process a priority equivalent to the inverse of its burst time, we can use a priority scheduling algorithm to achieve the same result as SJF.
-
This is why Shortest Job First is considered a special case of Priority Scheduling.
