Questions: 1. In your perspective, what makes counting semaphore primitives a good concurrency mechanism? 2. How does the structure of counting semaphore primitives differ from binary semaphore primitives? Part II: Binary Semaphore struct binary_semaphore enum (zero, one) value; queueType queue void semwaits (binary_semaphore a) if (8.value one) s.value = zero; else l /* place this process in s.queue */: /* block this proceas */: 1. void semsignalB (semaphore a) if (s. queue is empty ()) s.value = one; else i * remove a process P trom s.queue */: * place proces P on ready list */: Figure 2 A simple program structure of binary semaphore primitives. Questions: 3. Briefly explain the purpose of the semWaitB and semSignalB functions in Figure 2. 4. Based on Figures 1 and 2, which semaphore structure is easier to implement and why?

Instructions: Analyze the given concurrency mechanism figures and answer the corresponding questions for each type. Use 3-5 sentences in answering. Part I: Counting Semaphore struct semaphore ( int count; queueType queue; void semwait (semaphore s) s.count--; if (s.count < 0) /* place this process in s.queue /; 1* block thia process /: void semsignal (somaphore s) s.count++; if (s.count<= 0) ( /* remove a process P from s.queue */1 1* place procesa P on ready 1ist */: Figure 1. A simple program structure of counting semaphore primitives. Questions: 1. In your perspective, what makes counting semaphore primitives a good concurrency mechanism? 2. How does the structure of counting semaphore primitives differ from binary semaphore primitives?
