The producer and consumer processes share the following variables: Int n, Semaphore M=1 Semaphore E=n Semaphore F=0. The consumer process must execute __and before removing an item from buffer.

(a) signal(M), signal(F)

(b) signal(M), wait(F)

(c) Signal(F), wait(M)

(d) wait(F), wait(M)

The consumer process must execute wait(F), wait(M) and before removing an item from the buffer. In producer-consumer issues, producers can only churn out goods when there is room in the buffer, which means they must wait for consumers to use them up first.

Consumer Process before Removing an Item from the Buffer

Similar to producers, consumers can only use the product when it is produced.

Given, M = 1, E = n and F =0

Here, semaphore M is for mutual exclusion, semaphore E is for empty space in the buffer, and semaphore F is

used to define the space filled by the producer.

code for producer side:

while (true)

{

Produce()

Wait(E)

Wait(M)

Append()

Signal(M)

Signal(F)

}

Code for consumer side:

while (true) {

Wait(F)

Wait(M)

Consume()

Signal(M)

Signal(E)

}

Summary:

The producer and consumer processes share the following variables: Int n, Semaphore M=1 Semaphore E=n Semaphore F=0. The consumer process must execute ____ and before removing an item from the buffer. (a) signal(M), signal(F) , (b) signal(M), wait(F), (c) Signal(F), wait(M), (d) wait(F), wait(M)

Before removing an item from the buffer, the consumer process must run wait(F), wait(M), and.
