Long-term scheduler is called as job scheduler. Whereas medium-term scheduler is called as process swapping scheduler. In long-term scheduler, the process are selected from the job pool and these process are loaded into memory in order to execute.
What are the main differences between short term medium term and long term scheduler?
Short term scheduler ensures which program is suitable or important for processing. Medium term scheduler removes the processes from the memory. Long term scheduler regulates the programs which are selected to the system for processing. It is also referred to as CPU Scheduler.
What is a medium term scheduler used for?
Medium-term scheduling is a part of swapping. It removes the processes from the memory. It reduces the degree of multiprogramming. The medium-term scheduler is in-charge of handling the swapped out-processes.
What is the difference between long term scheduler and short term scheduler?
Long term scheduler takes jobs from a job pool and manage them. Short term scheduler takes process from a ready queue and context switch the CPU. Long term scheduler is known as JOB Scheduler.
Which is the most optimal scheduling algorithm?

| Answer:SJF – Shortest Job First |
Which algorithm is oldest fairest and widely used in modern OS?
Since Linux 2.6. CFS is the first implementation of a fair queuing process scheduler widely used in a general-purpose operating system. The Completely Fair Scheduler (CFS) uses a well-studied, classic scheduling algorithm called fair queuing originally invented for packet networks.
What is the role of scheduler?
Scheduler Job Responsibilities: Answers phones and emails, schedules and confirms appointments, and inputs customer data into company systems. Organizes workflow and appointment by reading and routing correspondence, collecting customer information, and managing assignments.
Which is the most optimal scheduling algorithm * 2 points?
Question 9 : The most optimal scheduling algorithm is :
- FCFS – First come First served.
- SJF – Shortest Job First.
- RR – Round Robin.
- None of the mentioned. View Answer Discuss with Members.
Can preemptive scheduling cause starvation?
Yes, pre-emptive scheduling may cause starvation. Let’s see Longest remaining time first scheme. It is pre-emptive scheduling. At any point of time, if any process having larger execution time or larger remaining time arrives, processor will switched to that process pausing current ongoing process.
What are the 3 types of scheduler?
There are three types of schedulers available :
- Long Term Scheduler : Long term scheduler runs less frequently.
- Short Term Scheduler : This is also known as CPU Scheduler and runs very frequently.
- Medium Term Scheduler :
Which scheduling is best in OS?
The FCFS is better for a small burst time. The SJF is better if the process comes to processor simultaneously. The last algorithm, Round Robin, is better to adjust the average waiting time desired. Round Robin quantum time will set it towards more SJF or FCFS value.
What makes a good scheduler?
They should be resourceful and creative in their approach to problems, and they need to identify in most cases the right person(s) within the team to help them resolve the problem quickly and efficiently. Schedulers should use a systematic approach to solve any problems they may confront during scheduling of projects.
What is another word for scheduler?
In this page you can discover 7 synonyms, antonyms, idiomatic expressions, and related words for scheduler, like: synchronization, scheduling, NQS, checkpointing, RTAI, NQSII and Wirecast.
What is the best scheduling algorithm?
What is the most optimal scheduling?
The most optimal scheduling algorithm is a fcfs first.
Which scheduling is starvation?
Starvation or indefinite blocking is phenomenon associated with the Priority scheduling algorithms, in which a process ready to run for CPU can wait indefinitely because of low priority.
Which scheduling algo causes starvation?
Pramod Soni : 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. That’s why SJF algorithm leads to starvation.
