In a batch operating system, three jobs are submitted for execution. each job involves and I/O activity, CPU time and another I/O activity of the same time span as the first. Job JOB1 requires a total 23ms, with 3ms CPU time;JOB2 requires requires a total time of 29 ms with 5ms CPU time; JOB3 requires a total time of 14 ms with 4ms CPU time. Illustrate their execution and find CPU utilization for uniprogramming and multiprogramming systems. Also,Graphical representations and numeric calculations are expected to be showned.
