The round-robin scheduling algorithm allocates CPU time to processes by sequentially assigning the CPU to processes of equal priority that are in the state of being able to use the CPU. (Not blocked) This works by appearing to evenly distribute the CPU amongst CPU ready processes. Processes that are waiting on something, such as an I/O event, particularly waiting on the user to press Enter, are not considered for allocation. Often, there is a priority assigned to the process, which factors in the allocation strategy. Processes that are mostly I/O intensive tend to have higher priority, giving them good response time. Processes that are mostly CPU intensive tend to have lower priority, so they don't interfere with overall system responsiveness.

Round robin scheduling program in java?
Round robin is the scheduling algorithm that is utilized by the CPU, or central processing unit, during the execution of the process. It is specifically designed for time sharing systems.
what are advantages and disadvantages of Round Robin scheduling algorithm?
Pure round robin scheduling processes A, then B, then C, then starts at A again. (A, B, C might be tasks in an operating system context, or devices in a master/slave control network, or whatever.) That is, pure round robin scheduling doesn't acknowledge priorities, and does not allow out-of-order processing. Real-life systems typically use a mixture of algorithms that, together, allow for prioritized and out-of-order processing while, on the other hand, trying to prevent starvation of lower priority items.
How do you calculate waiting time Round Robin algorithm?
To calculate the waiting time in the Round Robin scheduling algorithm, follow these steps: First, determine the completion time for each process by simulating the execution of processes in a cyclic manner for a fixed time quantum. Next, calculate the turnaround time for each process by subtracting the arrival time from the completion time. Finally, the waiting time for each process is found by subtracting the burst time from the turnaround time. The formula is: Waiting Time = Turnaround Time - Burst Time.
What is the schedule algorithm used in windows?
Windows operating systems primarily use a scheduling algorithm called the "Multilevel Feedback Queue" (MLFQ). This algorithm allows processes to be dynamically moved between different priority queues based on their behavior and requirements, which helps optimize CPU utilization and responsiveness. It employs various time slices for different priority levels, ensuring that both high-priority and lower-priority tasks receive appropriate processing time. Additionally, Windows also utilizes a round-robin approach within each priority level to fairly allocate CPU time among processes.

What CPU scheduling algorithm is used Windows NT?
Windows XP uses a quantum-based, preemptive priority scheduling algorithm
What is a multilevel scheduling?
Multilevel scheduling is a CPU scheduling algorithm that organizes processes into multiple priority levels or queues, allowing for different scheduling strategies at each level. Each queue can have its own scheduling algorithm, such as first-come, first-served or round-robin, enabling the system to optimize performance for various types of workloads. Processes are typically promoted or demoted between levels based on their behavior and resource needs. This approach enhances responsiveness and efficiency by balancing the needs of both high-priority and low-priority tasks.

What is virtual round robin CPU scheduling?
A variant of round robin scheduling is called selfish round robin scheduling. In selfish round robin, there is a maximum limit on the number of processes that can be placed in the round-robin queue (including the process being executed by the CPU). After that maximum is reached, newly entering processes are placed on a holding queue. Processes in the holding queue do not get any time slice of the CPU. When a process in the round-robin queue completes and leaves the system, the oldest process in the holding queue is allowed to enter the round-robin queue
Is the round robin CPU scheduling algorithm suitable for time sharing OS?
Yes, it is one of many scheduling algorithms suitable for time sharing.However it is not suitable for scheduling in a hard realtime OS that must consistently meet deadlines.
Advantages of Round Robin Scheduling?
It is the most simple scheduling algorithmn It is easy to implement in software If the processes are of varied length then it becomes slow.
what are advantages and disadvantages of Round Robin scheduling algorithm?
Pure round robin scheduling processes A, then B, then C, then starts at A again. (A, B, C might be tasks in an operating system context, or devices in a master/slave control network, or whatever.)

Which is best scheduling algorithm?
There isn't a single "best" scheduling algorithm, as the effectiveness of a scheduling algorithm depends on the specific requirements and constraints of the system in question. Common algorithms include Round Robin, Shortest Job First, and Priority Scheduling, each with its strengths and weaknesses. For real-time systems, Rate Monotonic Scheduling may be preferred, while for batch processing, Shortest Job First could be more efficient. Ultimately, the best choice depends on factors such as system load, response time requirements, and resource availability.
Example of round robin?
The round robin scheduling algorithm works by placing all processes in a circular queue and allotting each process a single time slice until all processes are completed. If process A required 2 time slices, process B required 1 time slice, and process C required 3 time slices the queue would be as follows: A > B > C > A > C > C.
Why is two-level scheduling commonly used?
It is a Computer Science term. Two-level scheduling is needed when memory is too small to hold all the ready processes. Some set of them is put into memory, and a choice is made from that set. From time to time the set of in-core processes is adjusted. This algorithm is easy to implement and reasonably efficient, certainly a lot better than, say, round robin without regard to whether the process was in memory or not.

One is weighted, the other is not. Simple as.
