The Bounded buffer problem is also known as __________.

Answer: The Bounded buffer problem is also known as the Producer - consumer problem.

Explanation:

The problem involves producer processes that place data items into a fixed-size buffer and consumer processes that remove items. The main synchronization challenges are:

• Preventing producers from adding items when the buffer is full.

• Preventing consumers from removing items when the buffer is empty.

• Protecting concurrent access to the shared buffer to avoid race conditions.

Typical synchronization solution:

• Use two counting semaphores (empty and full) to track available slots and filled slots.

• Use a mutex (binary semaphore) to ensure exclusive access when inserting or removing an item.

• Producer sequence: wait(empty), wait(mutex), add item, signal(mutex), signal(full).

• Consumer sequence: wait(full), wait(mutex), remove item, signal(mutex), signal(empty).

Why the other problems are different:

• Reader - writer problem focuses on allowing multiple readers but exclusive writers to protect shared data consistency; it is not about buffer capacity between producers and consumers.

• Dining Philosophers problem models resource allocation and potential deadlock between processes competing for limited resources; it addresses deadlock and starvation rather than managing a bounded buffer.
