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.

Write a python application using the concepts of multithreading for a flower

shop where flowers are delivered based on order using Synchronization.


Write a simulation program with Synchronization for the fruit market. The

farmer will be able to produce different types of fruits (apple, orange, grape,

and watermelon), and put them in the market to sell. The market has limited

capacity and farmers have to stand in a queue if the capacity is exceeded to

sell their fruits. Consumers can come to the market any time and purchase

their desired fruits; and if the fruits they want to buy runs out, they are

willing to wait until the supply of that kind is ready. (Hint: implementing

this market will encounter the producer and consumer problem, and it

probably needs multiple buffers for different kinds of fruits).
