Jump to level 1 Four processes execute on a system with a single CPU and a single I/O device. The system uses multiprogramming without time-sharing. Each process has a compute-bound phase of 40 time units followed by an I/O-bound phase of 20 units. A process cannot initiate the I/O phase until the I/O device becomes free The processes start executing in the order p1, p2, p3, p4. During the execution of all processes, the CPU is idle for Ex: 5 the I/O device is idle for Ex: 5 time units time units
