Detailed explanation-1: -Round-robin scheduling (Figure 7.151) allocates each task an equal share of the CPU time. In its simplest form, tasks are in a circular queue and when a task’s allocated CPU time expires, the task is put to the end of the queue and the new task is taken from the front of the queue.
Detailed explanation-2: -The Round robin scheduling algorithm is one of the CPU scheduling algorithms in which every process gets a fixed amount of time quantum to execute the process. In this algorithm, every process gets executed cyclically.
Detailed explanation-3: -Round robin is a pre-emptive algorithm. The biggest advantage of the round-robin scheduling method is that If you know the total number of processes on the run queue, then you can also assume the worst-case response time for the same process. This method spends more time on context switching.
Detailed explanation-4: -Round Robin is the preemptive process scheduling algorithm. Each process is given a fixed amount of time to complete, which is referred to as a quantum. Once a process has been completed for a given time period, it is preempted and another process begins to execute for that time period.
