Answer to Question #254053 in Computer Networks for Ikraam Kader

Question

Consider a system with 13 dedicated devices of the same type and all jobs currently
running on this system require a maximum of three devices to complete their
execution but they each run for long periods of time with just two devices and
request the remaining one only at the very end of the run. Assume that the job
stream is endless and that your operating systemà ƒ ƒ ƒ ¢ € ™s device allocation policy is a very
conservative one: No job will be started unless all the required drives have been
allocated to it for the entire duration of its run.
Explain what are the minimum and maximum numbers of devices that may be
idle as a result of this policy.

Answer 1

Regardless of the industry you work in, computers play a vital role in the processing. Computers are complex machines that manage multiple processes without you even seeing them. Allocation policy gives you more control over how devices are assigned processes. A maximum numbers of devices that may be idle is eight devices while minimum is five devices.
