In class, we used the following approach to demonstrate that you can use the TS instruction to implement general semaphores. sema_general_S22.JPG Suppose the initial value of value is 2. Please use one example to justify while(!s.hold); is necessary. 

Is the following solution correct to solve the critical section problem? Please briefly explain. Proc (int i) { while (TRUE){            compute;            while (turn != i);            critical_section;            turn = (i+1) mod 2; } } shared int turn; turn = 1; fork(proc, 1, 0); fork(proc, 1, 1);

The following questions are about virtual memory: a.What is Belady’s anomaly in the context of virtual memory? b.What is thrashing in the context of virtual memory?

We discussed the following problem in the class. X is a shared variable between process A and process B. Process B can only retrieves x AFTER process A updates x. PAPB_S22.JPG a.Please use P and V to solve the above problem. b.Please use a monitor and a conditional variable to solve this problem.

We discussed the following solution in the class. In the following solution, L and len are data shared by process P1 and P2. 1. deadlock_S22.JPG Please give one example to show why the solution is not correct. 2.Please use a monitor to solve the problem. 

Please briefly explain what will happen when a page fault occurs? 

Find the domain, intercepts and equations of all asymptotes for the following rational function:

Refer to the table below: Consumption Function  C = 120 + 0.8(Y-T) Planned Investment $ 200 Government Purchases $ 400 Taxes $ 400   What is equilibrium income?

Match each curve to the relationship that it demonstrates.

Prior to the 1972 election, many economists believed that the economy was close to potential output (Point A in the graph below). It is rumored that President Nixon pressured the  Federal Reserve Chairman Arthur Burns to use expansionary monetary policy (autonomous easing of the money supply) to make employment numbers look even better going into the election. A few years later, the oil shortage hit the United States, causing a significant supply shock. Which of the following explains why Nixon’s pressure on Burns was a bad idea in the long-run?
