The size of the Time Quantum
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.
A round robin algorithm processes a number of tasks, steps or items one by one in a cyclic fashion like so:1. For N items, n=0, 2, 3, ..., N-1, let nbe 0.2. Process step (item, task) n3. Compute n = (n+1) % N, where % is the modulo operator (the remainder of integer division)4. Proceed to step 2.
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.
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.
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.

distributed system doesn't have any global clock time. It uses some special schedule technique such as lampart's cycle and other 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.

I guess. It depends on their differences
