WebJan 31, 2024 · In this type of scheduling algorithm, if a newer process arrives, that is having a higher priority than the currently running process, then the currently running process is preempted. Example of Priority Scheduling. Consider following five processes P1 to P5. Each process has its unique priority, burst time, and arrival time. WebRound Robin Scheduling. Round Robin Scheduling algorithm designed for time-sharing systems. It is similar to FCFS scheduling but adding preemption to switch the processes after a small unit of time. A small unit of time is called a time quantum. A time quantum might be from 10 to 100 millisecond. How RR algorithm works: Ready queue as a FIFO … sunnyvale wastewater treatment plant

"WebThe FCFS scheduling technique is the simplest scheduling algorithm. In this scheduling, CPU schedules the processes on the basis of their arrival time. The processes are stored in a queue that follows a First In First Out (FIFO) structure. When a process arrives, it takes the CPU time and runs till it completes.
