Dаvid implemented а scheduling аlgоrithm, but he didn’t tell Aarоn which оne he decided to implement. To identify David’s algorithm, Aaron decided to schedule 3 processes, P1, P2, and P3, arriving at t=0, 1, 2, respectively. The following diagram represents when each process executes its CPU and I/O bursts. The times below represent the ending time of each block. For example P1 starts its first CPU burst at t=0 and ends it at t=2.
