In computing, the producer–consumer problem (also known as the bounded-buffer problem) is a classic example of a multi-process synchronization problem. The problem describes two processes, the producer and the consumer, who share a common, fixed-size buffer used as a queue.

3. Producer - Consumer Problem
Is a multi-process synchronization problem
Also known as the bounded-buffer problem
Two processes share a common buffer
Producer : One of them is producer puts information in
the buffer
Consumer : One of them is consumer takes information
out of the buffer

4. Real life Example
Picture 1: Full of items Picture 2: Lorry is empty
Lorry is
Empty

5. Real life Example
Picture 3 : Working for load Picture 4 : Loading

6. Real life Example
Picture 5 : Truck is full Picture 6 : Still many items

7. Real life Example
Picture 7 : Truck is full & unloaded Picture 8 : Uloading

8. Real life Example
Picture 9 : Truck is empty Picture 10 : Waiting

9. Real life Example
Picture: All Process

10. Solution for the Producer - Consumer
 Producer wants to put but buffer- full Go to sleep and wake up
when consumer takes one or more
 Consumer wants to take but buffer-empty go to sleep and wake up
when producer puts one or more
