Which Is The Best Scheduling Algorithm In Os

The main purpose of disk scheduling algorithm is to select a disk request from the queue of IO requests and decide the schedule when this request will be processed. In this method the memory wastage is minimal as the approach allocates the memory blocks with minimum memory wastage.

Goal of Disk Scheduling Algorithm.

Which is the best scheduling algorithm in os. Disk Scheduling Algorithms Given an array of disk track numbers and initial head position our task is to find the total number of seek operations done to access all the requested tracks if LOOK disk scheduling algorithm is used. The list of various disks scheduling algorithm is given below. The best fit memory allocation method the memory is traversed until a suitable empty block is found.

Below are different time with respect to a process. The definition of a multilevel feedback queue scheduler makes it the most general CPU-scheduling algorithm. Time at which process completes its execution.

Unfortunately it also requires some means of selecting values for all. Also write a program to find the seek sequence using LOOK disk scheduling algorithm. Time at which the process arrives in the ready queue.

Time required by a process for CPU execution. Minimal traveling head time. Example of Best Fit Method.

LOOK Disk Scheduling Algorithm. Scheduling of processeswork is done to finish the work on time. It can be configured to match a specific system under design.
