Which of the following disk scheduling strategies is likely to give the best throughput?
Farthest cylinder next
Nearest cylinder next
First come first served
Option (B) and (D) both are acceptable. For more details please check comment of @Vicky rix ji.
Hi @sushmita, vaishali jhalani and Puja Mishra ji,
First of all thanks for raising good point. But could you please provide some counter example where Elevator algorithm will perform better then Nearest cylinder next ?
As long as the block request string is given, we cannot decide between B) and D)
B) is not always the best EX:
throughput put depends on the number of requests served per second as we always go for the shortest reach SSTF Does this best as it tries to serve the maximum number of processes in less time
Thank you @Vicky rix ji.
If "Rounded to the nearest integer" is the ...
