Flashcards do conjunto (4)
- 1What are the advantages and disadvantages of FCFS scheduling algorithm?Poor in perfomance. Avarage waiting time is high. Short processes might have to wait for a long time
- 2What are the advantages/disadvantages and disadvantages of the SJF scheduling algorithm?Adv: Simplicity. Minimizes waiting time.
Disadv: process starvation. Total time must be known in beforehand - 3What are the advantages/disadvantages and disadvantages of the RR scheduling algorithm?adv: Ensures to go through all ready tasks. Easy to implement. No starvation.
dis: Not always ideal to give the same CPU time to highly interactive and CPU bound processes. HIGH avarage turnaround time - 4How can Multilevel queues be used to partition CPU time?It does time slicing amon multilevel queues. Foreground can be given 80% of CPU time for example.
