Suppose we have multiprogrammed batch system. Each job alternates between performing computation and waiting for I/O. The wait times are the amount of time it takes for the I/O request to processes and is therefore the minimum amount of time that a job would need to wait. Suppose all jobs are loaded into memory by the monitor, specified below. (Listed in the batch in order)

Compute 13s, Wait 6s, Compute 18s Compute 6s, Wait 13s, Compute 9s, Wait 24s, Compute 3s

Compute 24s, Wait 30s, Compute 4s, Wait 6s, Compute 20s

Compute 20s, Wait 21s, Compute 17s Compute 28s, Wait 12s, Compute 15s, Wait 24s, Compute 4s

a) The turnaround time for each job (The actual time to complete the job)

b) The throughput of the system (Average number of jobs completed per second)

c) The processor utilization (Percentage of time the processors is executing code)
