In a batch operating system, four jobs JOB1, JOB2, JOB3, JOB4 are submitted for execution. Each job involves an I/0 activity, followed by a CPU time, followed by another I/O activity of the same time span as the first. Each job is associated with a different I/O device. JOB1 requires a total of 11 ms, with 1 ms CPU time. JOB2 requires 10 ms total time with 2 ms CPU time. JOB3 requires 56 ms total time with 8 ms CPU time. JOB4 requires 19 ms total time with 5 ms CPU time. Assume a uni-programming system and answer the following:
