What is the solution to starvation problem?
A possible solution to starvation is to use a scheduling algorithm with priority queue that also uses the aging technique. Aging is a technique of gradually increasing the priority of processes that wait in the system for a long time.
What is starvation in shortest job first?
The main problem with the shortest job first algorithm is starvation [1], [2]. If there is a steady supply of short process, the long process may never get the chance to be executed by the processor. The longer a process is waiting in the queue, the higher the priority it accrues, thereby preventing its starvation.
What is starvation in scheduling and what is its solution?
Starvation is a phenomenon in which a process that is present in the ready state and has low priority, keeps on waiting for the CPU allocation because some other process with higher priority comes with due respect to time.
Why shortest job first and priority based scheduling algorithms could result in starvation?
In Priority based scheduling if higher priority process keep on coming then low priority process will suffer from starvation. In Shortest remaining time first(SRTF) process with shortest burst time will execute first because of this process with high burst time may suffer from starvation.
What is the solution to starvation Mcq operating system?
| Q. | What is the solution to starvation? |
|---|---|

| C. | resource preemption be done instead |
| D. | all of the mentioned |
| Answer» a. the number of rollbacks must be included in the cost factor |
What is the solution of starvation Mcq?
What is starvation Which of the following scheduling algorithms could result in starvation a first come first served b shortest job first C round robin D priority?
Shortest job first and priority-based scheduling algorithms could result in starvation. 4 • The time quantum is 1 millisecond: Irrespective of which process is scheduled, the scheduler incurs a 0.1 millisecond context-switching cost for every context-switch. This results in a CPU utilization of 1/1.1 * 100 = 91\%.
How to solve the problem of starvation problem in SJF scheduling algorithm?
One possible solution to this problem is to avoid more process to be scheduled in job pool once it is full i.e., Scheduler must wait until job pool is completely empty before it can get more process for execution. It is difficult to find a solution to starvation problem in SJF scheduling algorithm.
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 shortest job first algorithm?
From my remembered OS time in College, Shortest Job First is the non-preemptive algorithm that can happen to provoke starvation. How? To put it simple, if you have a very long process and short processes keep coming up, SJF will swap to the short ones and keep the long process in the waiting pipe.
What is starvation in CPU priority scheduling?
Before getting into the details of Starvation, let’s have a quick overview of Priority Scheduling algorithms. In Priority scheduling technique, we assign some priority to every process we have and based on that priority, the CPU will be allocated and the process will be executed.
