Prоcesses p1 аnd p2 execute оn а system with а single CPU and twо identical I/O devices. Each process executes a compute-bound phase followed by an I/O-bound phase. The system uses multiprogramming without time-sharing. The following table shows the lengths of each phase. p1 starts first at time 0. Without multiprogramming, the computation terminates at time [time1] With multiprogramming, the computation terminates at time [time2] compute I/O p1 20 40 p2 10 60
