WebThe Producer-Consumer problem is a classical multi-process synchronization problem, that is we are trying to achieve synchronization between more than one process. There is one Producer in the producer-consumer problem, Producer is producing some items, whereas there is one Consumer that is consuming the items produced by the Producer.
