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: -In Round Robin Scheduling, the CPU is assigned to the process based on FCFS for a fixed amount of time. This fixed amount of time is called a time quantum or time slice. After the time quantum expires, the running process is preempted and sent to the ready queue.

Detailed explanation-3: -Round Robin is the preemptive process scheduling algorithm. Each process is provided a fix time to execute, it is called a quantum. Once a process is executed for a given time period, it is preempted and other process executes for a given time period.

Detailed explanation-4: -Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing. As the term is generally used, time slices (also known as time quanta) are assigned to each process in equal portions and in circular order, handling all processes without priority (also known as cyclic executive).

Detailed explanation-5: -FCFS is the simplest and easiest CPU scheduling algorithm, managed with a FIFO queue. FIFO stands for First In First Out. The FCFS scheduling algorithm places the arriving processes/jobs at the very end of the queue. So, the processes that request the CPU first get the allocation from the CPU first.
