Is applications are dependent on operating systems?

It always depends upon operating system. But it does not depend upon application software.it provides the path to execute or to run the application software.

What is the drawback of SJF algorithm?

Disadvantages/Cons of SJF SJF can’t be implemented for CPU scheduling for the short term. It is because there is no specific method to predict the length of the upcoming CPU burst. This algorithm may cause very long turnaround times or starvation. Requires knowledge of how long a process or job will run.

Which of the following algorithm is also known as Shortest Time to go?

Shortest remaining time, also known as shortest remaining time first (SRTF), is a scheduling method that is a preemptive version of shortest job next scheduling. In this scheduling algorithm, the process with the smallest amount of time remaining until completion is selected to execute.

What are application programs in operating system?

Software that processes data for the user. Except for “system software,” which provides the infrastructure in the computer (operating system, utilities and related components), all software programs are application programs.

Why is the shortest job first optimal?

SJF is a scheduling algorithm that assigns to each process the length of its next CPU burst/execution time. SJF is provably optimal, in that for a given set of processes and their CPU bursts/execution times it gives the least average waiting time for each process.

What is shortest job first preemptive?

Shortest Job First – Preemptive Scheduling Algorithm is an algorithm in which the processor is allocated to the job having minimum CPU burst time, but the job can be preempted (Replaced) by a newer job with shorter burst time.

Which of the following algorithm tends to minimize the process flow time?

Discussion Forum

What is the main drawback of the SJF shortest job first and SRTF shortest remaining time first scheduling algorithms?

Both SJF and SRJF are practically not feasible as it is not possible to predict the burst time of the processes. Both SJF and SRJF may lead to process starvation as long processes may be held off indefinitely if short processes are continually added.

What is shortest job first in Java?

Shortest Job First (SJF) is an algorithm in which the process having the smallest execution time is chosen for the next execution. This scheduling method can be preemptive or non-preemptive.

What is shortest job first scheduling?

What is Shortest Job First Scheduling? Shortest Job First (SJF) is an algorithm in which the process having the smallest execution time is chosen for the next execution. This scheduling method can be preemptive or non-preemptive. It significantly reduces the average waiting time for other processes awaiting execution.

What is the use of SJF scheduling algorithm?

SJF Scheduling is associated with each job as a unit of time to complete. This algorithm method is helpful for batch-type processing, where waiting for jobs to complete is not critical. There are basically two types of SJF methods 1) Non-Preemptive SJF and 2) Preemptive SJF.

Which algorithms are based on non-preemptive scheduling?

Algorithms based on non-preemptive scheduling are: Shortest Job First (SJF basically non preemptive) and Priority (non preemptive version), etc.
