2. (10 points) The following are the CPU and I/O behavior of three processes, timings irn seconds Process P1 has 1 second CPU burst followed by 3s l/O followed by 1s CPU burst Process P2 has 2 second CPU burst followed by 2s l/O followed by 2s CPU burst Process P2 has 4 second CPU burst followed by 1s I/O followed by 4s CPU burst Please provide approximate sketches of Gantt charts, and average turnaround times for the following scheduling algorithms: 1. Round Robin with a smallish time quanta (below 0.1s)
