17 marksl The sequence of steps given below is used for the Bounded-Buffer Producer/Consumer problem. The steps use the following 4. mutex access buffer semaphore full semaphore emptycount buffer empty spots, initial is N count buffer filled spots, initial is zero Producer Steps produce item wait/decrease empty wait/decrease access buffer put item into buffer signal/increase access buffer signal/increase full Consumer Steps wait/decrease full wait/decrease access buffer get item from buffer signal/increase access buffer signal/increase empty use item a) 2 marks] Explain the potential problem if the mutex access_buffer is not included in the sequence of steps for the producer and consumer b) [2 marks] What is the potential problem if the sequence of steps for the producer is changed such that the mutex access buffer step is performed before the semaphore empty step? c) [3 marks] Explain why the two semaphores full and empty are used for the Bounded-Buffer Producer/Consumer
