Assume that four jobs, A-D, are in the READY queue at Time 0 and require the CPU cycles listed below. Using the SJN algorithm, the job is run first. Job: A B C D CPU cycle: 5 2 6 4

"B" is the answer for the above question.

Explanation:

The full form of SJN is the shortest job next algorithm which is working to execute the process if there is more than one process present in the ready queue.This processor takes that process which has the smallest execution time among the process which is present in the ready queue.The above question states the four processes, in which the B process has the smallest execution time. So the B process will be executed first.The above question asked which is executed first. So "B" is the answer.
