Consider the procedure below for the Producer-Consumer problem which u...

Initially, there is no element in the buffer.
Semaphore s = 1 and semaphore n = 0.
We assume that initially control goes to the consumer when buffer is empty.
semWait(s) decrements the value of semaphore ‘s’ . Now, s = 0 and semWait(n) decrements the value of semaphore ‘n’. Since, the value of semaphore ‘n’ becomes less than 0 , the control stucks in while loop of function semWait() and a deadlock arises.

Thus, deadlock occurs if the consumer succeeds in acquiring semaphore s when the buffer is empty.

Consider the following solution to the producer-consumer synchronization problem. The shared buffer size is N. Three semaphores empty, full and mutex are defined with respective initial values of 0, N and 1. Semaphore empty denotes the number of available slots in the buffer, for the consumer to read from. Semaphore full denotes the number of available slots in the buffer, for the producer to write to. The placeholder variables, denoted by P, Q, R and S, in the code below can be assigned either empty or full. The valid semaphore operations are: wait() and sigmal().Which one of the following assignments to P, Q, R and S will yield the correct solution?

Consider two processes P1 and P2 accessing the shared variables X and Y protected by two binary semaphores SX and SY respectively, both initialized to 1. P and V denote the usual semaphone operators, where P decrements the semaphore value, and V increments the semaphore value. The pseudo-code of P1 and P2 is as follows : P1 :While true do { L1 : ................ L2 : ................ X = X + 1; Y = Y - 1; V(SX); V(SY);}P2 :While true do {L3 : ................L4 : ................Y = Y + 1;X = Y - 1;V(SY);V(SX);}Q.In order to avoid deadlock, the correct operators at L1, L2, L3 and L4 are respectively

The P and V operations on counting semaphores, where s is a counting semaphore, are defined as follows:P(s) : s = s - 1; if (s 0) then wait;V(s) : s = s + 1; if (s = 0) then wakeup a process waiting on s;Assume that Pb and Vb the wait and signal operations on binary semaphores are provided. Two binary semaphores Xb and Yb are used to implement the semaphore operations P(s) and V(s) as follows:P(s) : Pb(X b); s = s - 1; if (s 0) { Vb(Xb) ; Pb(Yb) ;}else Vb(Xb);V(s) : Pb(Xb) ; s = s + 1; if (s = 0) Vb(Yb) ;Vb(Xb) ;The initial values of Xb and Yb are respectively

Three concurrent processes X, Y, and Z execute three different code segments that access and update certain shared variables. Process X executes the P operation (i.e., wait) on semaphores a, b and c; process Y executes the P operation on semaphores b, c and d; process Z executes the P operation on semaphores c, d, and a before entering the respective code segments. After completing the execution of its code segment, each process invokes the V operation (i.e., signal) on its three semaphores. All semaphores are binary semaphores initialized to one. Which one of the following represents a deadlock-free order of invoking the P operations by the processes?
