Please do not copy and paste the answer that has already been provided in the textbook solutions. That answer is confusing and didn't help me understand the problem. Thank you in advance.

A multiprocessor with eight processors has 20 attached tape drives. There is a large number of jobs submitted to the system that each require a maximum of four tape drives to complete execution. Assume that each job starts running with only three tape drives for a long period before requiring the fourth tape drive for a short period toward the end of its operation. Also assume an endless supply of such jobs. a. Assume t When a job is started, four drives are assigned immediately and are not released until the job finishes. What is the maximum number of jobs that can be in progress at once? What are the maximum and minimum number of tape drives that may be left idle as a result of this policy? he scheduler in the OS will not start a job unless ther e are four tape drives available.
