Several cpu-scheduling algorithms, Operating System

Assignment Help:

Q. Several CPU-scheduling algorithms are parameterized for instance the RR algorithm requires a parameter to indicate the time slice. Multilevel response queues require parameters to define the number of queues the scheduling algorithms for every queue the criteria used to move processes between queues and so on. These algorithms are consequently really sets of algorithms for instance the set of RR algorithms for all time slices and so on. One set of algorithms may comprise another (for instance the FCFS algorithm is the RR algorithm with an infinite time quantum).What (if any) relation embraces between the following pairs of sets of algorithms?

1 Priority and SJF

2 Multilevel feedback queues and FCFS

3 Priority and FCFS

4 RR and SJF

Answer:

1 The shortest job has the highest priority

2 The lowest level of MLFQ is FCFS.

3 FCFS provides the highest priority to the job having been in existence the longest.

4 None.
