Five jobs arrive nearly simultaneously for procesiing and their estimated CPU cycles are, respectivley: Job A=12, Job B=2, Job C=15, Job D=7, and Job E=3 ms.

Using fcfs, and assuming the difference in arrival time is negligible, in what order would they be processed?

Please show how the answer was determined.
