What is the main disadvantage of priority scheduling?

The major disadvantage of priority scheduling is the process of indefinite blocking or starvation. This problem appears when a process is ready to be executed but it has to wait for the long time for execution by CPU because other high priority processes are executed by the CPU.

What is the disadvantage of priority scheduling?

Following are the disadvantages of priority scheduling: We can lose all the low-priority processes if the system crashes. This process can cause starvation if high-priority processes take too much CPU time. The lower priority process can also be postponed for an indefinite time.

Which is not advantage of priority scheduling?

Which of the following is not an advantage of a priority queue? Explanation: In worst case, the entire queue has to be searched for the element having the highest priority. This will take more time than usual. So deletion of elements is not an advantage.

What are the disadvantages of priority scheduling convoy effect is there?

Disadvantage of FCFS is convoy effect. Convoy effect is that where larger processes come first and penalize short processes then the total average waiting time is high. Average waiting time is high because of the convoy effect.

What is not a disadvantage of priority scheduling in operating systems?

Interrupt handling is not a disadvantage of priority scheduling in OS. Explanation: 'Priority scheduling' can be defined as a non-preemptive algorithm. It is considered to be one of the most commonly used 'scheduling algorithms' in batch processing systems.

3.16 Advantage and Disadvantage of Priority scheduling algorithm in os in hindi with examples

What is Priority scheduling?

Priority scheduling is a method of scheduling processes based on priority. In this method, the scheduler chooses the tasks to work as per the priority, which is different from other types of scheduling, for example, a simple round robin.

Is a major problem with priority based scheduling algorithm?

In priority scheduling algorithm, a major problem to be considered is the starvation of a process i.e. a process which is ready to be executed but is waiting for the CPU because of its low priority. This can lead to the indefinite waiting of the low-priority processes.

What is the disadvantage of priority scheduling Mcq?

7) One of the disadvantages of the priority scheduling algorithm is that :a) it schedules in a very complex mannerb) its scheduling takes up a lot of timec) it can lead to some low priority process waiting indefinitely for the CPUd) None of theseView AnswerAnswer: cExplanation: None.

What are advantages and disadvantages of FCFS SJF priority scheduling?

What are the disadvantages of round robin scheduling?

What are the disadvantages of SJF scheduling algorithm?

Disadvantages of SJF

Used for long-term scheduling in a batch system. Can't implement this algorithm for CPU scheduling for the short term as we can't predict the length of the upcoming CPU burst. Cause extremely long turnaround times or starvation. Knowledge about the runtime length of a process is necessary.

What are the disadvantages of schedule?

What is the disadvantage of using FCFS?

Because FCFS is so simple, it does not offer some of the more complex features of other order scheduling methods. We will discuss these drawbacks, including; long waiting time, favored CPU over I//O processing, lower device utilization, and incompatibility with time-sharing systems.

What are the advantages of priority scheduling algorithm?

Advantages of priority scheduling

Easy to use scheduling method. Processes are executed on the basis of priority so high priority does not need to wait for long which saves time. This method provides a good mechanism where the relative important of each process may be precisely defined.

What are the advantages and disadvantages of round robin?

Advantages: Saves the eight jobs that would be cut out in a straight 24-player draw. Only a slight increase in the number of total matches for the event. Disadvantages: Fans have a hard enough time adjusting to a simple round-robin plus knockout format.

Is Priority Scheduling preemptive?

Priority scheduling is a non-preemptive algorithm and one of the most common scheduling algorithms in batch systems. Each process is assigned a priority. Process with highest priority is to be executed first and so on.

What is the problem encountered in priority scheduling explain the solution it?

Problem. In priority-based scheduling algorithms, a major problem is indefinite block, or starvation. A process that is ready to run but waiting for the CPU can be considered blocked. A priority scheduling algorithm can leave some low-priority processes waiting indefinitely.

What is starvation in priority scheduling?

Starvation or indefinite blocking is a phenomenon associated with the Priority scheduling algorithms, in which a process ready for the CPU (resources) can wait to run indefinitely because of low priority.

What is starvation discuss the problem of starvation in priority scheduling?

Starvation or indefinite blocking is a phenomenon associated with the Priority scheduling algorithms. A process that is present in the ready state and has low priority keeps waiting for the CPU allocation because some other process with higher priority comes with due respect time.

What is the disadvantage of FIFO scheduling algorithm?

Short jobs(process) may have to wait for long time. Important jobs (with higher priority) have to wait. cannot guarantee good response time.

What is a disadvantage of the SSTF scheduling algorithm?

Starvation may occur for requests far from head. In SSTF high variance is present in response time and waiting time. Frequent switching of the Head's direction slows the algorithm.

What are the disadvantages of FCFS scheduling algorithm as compared to SJF scheduling?

The disadvantage of this algorithm is that long processes may never be processed by the system and may remain in the queue for very long time leading to starvation of processes. If two processes have same burst time then the tie is broken using FCFS, i.e., the process that arrived first is processed first.
