What is the most efficient scheduling algorithm?
The most common scheduling algorithms are: Earliest Deadline First (EDF) and Least Laxity First (LLF). They are optimal scheduling algorithms for single processor system, but problem arises when algorithms are used for multiprocessor system.
Which is fastest scheduling algorithm?
Differences:
| Shortest Job First: | Shortest Remaining Job First: |
|---|---|
| It is a non-preemptive algorithm. | It is a preemptive algorithm. |
| It is slower in execution than SRJF. | It is faster in execution than SJF. |
| It leads to comparatively lower throughput. | It leads to increased throughput as execution time is less. |
Which scheduling algorithm is used?
Six types of process scheduling algorithms are: First Come First Serve (FCFS), 2) Shortest-Job-First (SJF) Scheduling, 3) Shortest Remaining Time, 4) Priority Scheduling, 5) Round Robin Scheduling, 6) Multilevel Queue Scheduling.

Which of the following algorithms works by priority?
Which of the following algorithms work based on priority? Explanation: The preemptive scheduling is based on priority where a scheduler may preempt a low priority running process anytime when a high priority process enters into a ready state.
Which scheduling algorithm is used in Mac?
Mac OS X supports both the multilevel feedback queue scheduling and round-robin (RR) scheduling algorithm. The multilevel feedback queue scheduling algorithm partitions the ready queue into several separate queues and allows a process to move between queues.
What happens in priority scheduling algorithm?
Priority Scheduling is a method of scheduling processes that is based on priority. In this algorithm, the scheduler selects the tasks to work as per the priority. The processes with higher priority should be carried out first, whereas jobs with equal priorities are carried out on a round-robin or FCFS basis.
Which of the following algorithms work based on priority?
For some of them, even the “first-come, first-served” (FCFS) rule could be “the most efficient algorithm”. FYI, there are a lot of standardized scheduling problems, which are discussed in the Pinedo’s textbook (you are referred to this page: https://books.google.com.sg/books?id=EkpDak9kEs0C&hl=en , if you like).
What is first come first serve scheduling algorithm?
First Come First Serve (FCFS) Jobs are executed on first come, first serve basis. It is a non-preemptive, pre-emptive scheduling algorithm. Easy to understand and implement. Its implementation is based on FIFO queue. Poor in performance as average wait time is high.
What is real-time system optimum scheduling algorithm?
A Real-Time system optimum scheduling algorithm must have abounded response times. One of the classic responses of Real-Time system respond to over was the Apollo Guidance Computer was 1202 to alarm was informing the astronauts that some of the navigation task were being dropped which the critical IMU and control task continued.
Are multiple-level queues an independent scheduling algorithm?
Multiple-level queues are not an independent scheduling algorithm. They make use of other existing algorithms to group and schedule jobs with common characteristics. Multiple queues are maintained for processes with common characteristics. Each queue can have its own scheduling algorithms.
