What is the producer-consumer problem in OS?
The Producer-Consumer problem is a classic problem this is used for multi-process synchronization i.e. synchronization between more than one processes. In the producer-consumer problem, there is one Producer that is producing something and there is one Consumer that is consuming the products produced by the Producer.
How semaphores and monitors are used to solve producer consumer problem?
Solution to Producer Consumer problem using Monitors. Monitors make solving the producer-consumer a little easier. Mutual exclusion is achieved by placing the critical section of a program inside a monitor. Once inside the monitor, a process is blocked by the Wait and Signal primitives if it cannot continue.
How is memory shared between producer and consumer?
The same memory buffer is shared by both producers and consumers which is of fixed-size. The task of the Producer is to produce the item, put it into the memory buffer, and again start producing items. Whereas the task of the Consumer is to consume the item from the memory buffer.
Who is the producer in the producer-consumer problem?
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. The same memory buffer is shared by both producers and consumers which is of fixed-size.
When is the producer not allowed to consume data?
The following are the problems that might occur in the Producer-Consumer: The producer should produce data only when the buffer is not full. If the buffer is full, then the producer shouldn’t be allowed to put any data into the buffer. The consumer should consume data only when the buffer is not empty.
What is the pseudo code for the producer?
The following is the pseudo-code for the producer: The above code can be summarized as: while () is used to produce data, again and again, if it wishes to produce, again and again. produce () function is called to produce data by the producer.
