What is the maximum number of jobs that can be in progress at once? (1 point) b) Compute the maximum and minimum number of tape drives that may be left idle as a result of this policy
An octa-core processor has 83 attached tape drives. There is a large number of jobs submitted to the
system that each of them requires a maximum of 5 tape drives to complete execution. Assume each job
starts running with only 4 tape drives for a long period before requiring the 5th tape drive for a short period
towards the end of its operation. When a job is started, 5 drives are assigned immediately and are not
released until the job finishes. Assume that the scheduler in the OS will not start a job unless there are 5
tape drives available. Also assume an endless supply of such jobs.
