A shared variable x, initialized to zero, is operated on by four concurrent processes W, X, Y, Z as follows. Each of the processes W and X reads x from memory, increments by one, stores it to memory, and then terminates. Each of the processes Y and Z reads x from memory, decrements by two, stores it to memory, and then terminates. Each process before reading x invokes the P operation (i.e., wait) on a counting semaphore S and invokes the V operation (i.e., signal) on the semaphore S after storing x to memory. Semaphore S is initialized to two. What is the maximum possible value of x after all processes complete execution?
Consider a process executing on an operating system that uses demand paging. The average time for a memory access in the system is M units if the corresponding memory page is available in memory, and D units if the memory access causes a page fault. It has been experimental measured that the average time taken for a memory access in the process is X units. Which one of the following is the correct expression for the page fault rate experienced by the process?

Assume a memory access to main memory on a cache "miss" takes 30 ns and a memory access to the cache (on a cache "hit") takes 3 ns. If 80% of the processor's memory requests results in a cache "hit", what is the average memory access time?
Consider the following statements for dynamic characteristics of a measurement system: 1. Fidelity is defined as the degree to which a measurement system indicates changes in the measured quantity without any dynamic error. 2. Dynamic error is the difference between the true value of the quantity changing with time and the value indicated by the measurement system if no static error is assumed. 3. Measuring lag is the retardation in the response of a measurement system to changes in the measured quantity. Which of the above statements are correct?
