FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -Round Robin (RR) The simplest preemptive scheduling algorithm is round-robin, in which the processes are given turns at running, one after the other in a repeating sequence, and each one is preempted when it has used up its time slice.

Detailed explanation-4: -When the CPU is idle, the operating system must select the processes in main memory (ready queue) for execution and allocate the CPU to one of these processes. This kind of selection is called the short-term scheduler (CPU scheduler).

Detailed explanation-5: -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.
