Final answer:
Bounded capacity and Unbounded capacity queues refer to the fixed or infinite size of the queue, respectively, and represent User defined buffering. These concepts are important in computer science to manage data flows and workloads in applications.
Step-by-step explanation:
Bounded capacity and Unbounded capacity queues refer to the limits placed on the number of items that can be stored in the queue. A bounded capacity queue has a fixed size, meaning it can hold only a certain number of items before it becomes full and is unable to accept new items. On the other hand, an unbounded capacity queue is assumed to have an infinite size, so it can grow indefinitely as new items are added. These concepts are typically found in the context of computer science, particularly in the study of data structures and algorithms.
The correct answer to the student's question is c) User defined buffering. This is because the capacity of a queue, whether it is bounded or unbounded, is generally set by the user or the system designer. It is a design choice made based upon the requirements of the application and available system resources. Buffered queues are used to handle varying workloads and to smooth out temporary spikes in the flow of data or tasks.
