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.

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.
