Unbounded vs Bounded Capacity Queues:
Unbounded and bounded capacity queues are two types of queues that are commonly used in computer science and programming. Let's explore the differences between these two types of queues.

Bounded Capacity Queue:
- A bounded capacity queue has a fixed size limit, meaning it can only hold a specific number of elements.
- Once the queue reaches its maximum capacity, any attempt to add more elements will result in an overflow condition.
- Bounded capacity queues are often used when there is a limited amount of memory available, or when it is important to control the amount of data being processed at any given time.

Unbounded Capacity Queue:
- An unbounded capacity queue, on the other hand, does not have a fixed size limit.
- It can grow dynamically to accommodate any number of elements that are added to it.
- Unbounded capacity queues are useful in situations where the amount of data being processed is not known in advance, or when there is a possibility of a large amount of data being processed.

Automatic Buffering:
- Unbounded capacity queues are often referred to as "automatic buffering" because they automatically handle the storage and retrieval of elements without the need for manual intervention.
- This makes them convenient to use in situations where the amount of data being processed can vary unpredictably.
In conclusion, bounded capacity queues are limited in size and can result in overflow conditions if the size limit is exceeded, while unbounded capacity queues can dynamically grow to accommodate any number of elements. The choice between the two types of queues depends on the specific requirements of the system being designed.
