2 ) Consider two processes PO and P1 which shares a global variable 'flag'. The value of flag is either 0 or 1 where 0 indicates "PO is permitted to enter into critical section" and 1 indicates for P1. Assume PO and P1 are concurrent processes which are executing the following code with initial value of flag as 0. while(1) { While (flag!=i); flag=1-i; } If PO starts executing first, which of the following holds by the above execution? A) Mutual Exclusion B) B) Progress C) C) Bounded waiting D) D) Both (A) and (C) Justify your answer.
In a computer system five processes are attempting to proceed with three resource types. The total units of system resources are: (8,9,7). The maximum demands for every process are: P1(3,1,1), P2(3,3,2), P3(5,3,2), P4(5,1,2), P5(8,4,3). The current allocation is: P1 (0,1,1), P2 (2,1,1), P3 (3,1,2), P4 (1,1,1), and P5 (2,3,2). Is this state a safe state? Explain your answer. Please explain in great detail so i can understand .
a)Consider the producer-consumer problem, Assume that the Consumer Process happens to run first and this process is allowed to run for about 10ms (it means that its running time can be very long). Describe what happens and explain any changes to any of the shared variables, and the flow of control (which statements in the Consumer Process execute). b) Assume that the Consumer Process is swapped out, and the Producer Process gets its chance to run, and the Producer Process is allowed to run for about 10ms (it means that its running time can be very long). Describe what happens and explain any changes to any of the shared variables, and the flow of control (which statements in the Consumer Process execute).
Question 3: On planet Z, a hybrid cooling system is to be built consisting of a cooling fan unit (F) and an air conditioning unit (C). You need to create a system that controls these two features depending on certain conditions. Assume that there are four sensors: Input (4 variables) T= 1 indicates that the temperature is high, 0 if not H= 1 indicates it is humid, O if not D= 1 indicates that it is day, O if night w = 1 indicates it is winter, O if not [Note: You need to maintain the input order as THDW with T as the MSB and W as the LSB] Output (2 variables) F = 1 indicates that the cooling fan unit is ON C= 1 indicates that the Air Conditioning Unit is ON. You have to consider the following conditions: The operation of the Air Conditioner requires a high temperature but the cooling fan works at all temperatures. The Air Conditioner will ONLY work at night and the cooling fan will work during both day and night.
Suppose that an operating system supports two kinds of sequential processes: high-priority interactive processes, and low-priority non-interactive processes. The behavior of the high-priority processes is to alternate between periods of computation of duration Tc and periods of blocking (waiting for input) of duration Tb. The behavior of the low-priority processes is to compute constantly, with no blocking. The operating system’s scheduling policy is round-robin with a quantum q, where Tc < q. Scheduling decisions are made only when a quantum expires, or when the running process blocks. The scheduler selects a low-priority process to run only if no high-priority processes are ready. Suppose there is one high-priority process and one low-priority process in the system, and that both processes will run for a long time. For what fraction of the time does the low-priority process run?

Race conditions are possible in many computer systems. Consider an accounting system of an organization where multiple users have access to an account to which they can either deposit or withdraw from: deposit(amount) and withdraw(amount). These two functions are passed the amount that is to be deposited or withdrawn from the account balance. Assume that Mary and Joe are employees who have access to this account. Currently, the balance in the account is $3000. If Mary executes deposit(500) and simultaneously Joe executes withdraw(300) from the account, describe how a race condition is possible and what might be done to prevent the race condition from occurring. Show the possible balances with race condition and when race condition is prevented.

Suppose processes P1-P4 with the given priorities and resource allocations. 1 is the highest priority and 4 is the lowest priority. Let us also assume that the "no preemption" condition is now relaxed by allowing preemption of resources by processes of higher priority. For example, P3 may preempt P2 or P4 if it needs a resource which they are holding. If P3 preempts one of these processes, say P4, then P4 release all the resources it is holding. Show one sequence of events in which resources are allocated to the 4 processes and the resulting preemptions, if any, until all new requests are serviced. Current allocations are shown below. Each resource has 4 instances. Try to minimize the preemptions as they are expensive. Process ID Process Priority Current allocation New request R1 R2 R1 R2 P1 1 2 1 2 1 P2 3 0 1 1 0 P3 2 1 1 0 1 P4 4 1 1 2 1
