Question

Which of the following algorithms tends to minimize the process flow time ?

a) First come First served
b) Shortest Job First
c) Earliest Deadline First
d) Longest Job First

Answer 1

The Shortest Job First (SJF) algorithm minimizes process flow time by executing the shortest available processes first, which reduces the total time processes spend in the queue.

Step-by-step explanation:

The algorithm that tends to minimize the process flow time is Shortest Job First (SJF). This algorithm selects the process with the shortest execution time from the queue and executes it first. By focusing on completing shorter tasks, SJF reduces the overall process flow time, which is the total time from when a process enters the queue until it's completed. In contrast, a First Come First Served (FCFS) approach could lead to longer waiting times for short processes if a long process arrives first. Earliest Deadline First (EDF) is prioritized on meeting deadlines rather than reducing flow time. Longest Job First (LJF) would increase process flow time as it does the opposite of SJF.
