The correct answer is Ring Buffer.

Explanation:

A Circular Queue is often referred to as a Ring Buffer due to its circular structure, which allows for efficient storage and retrieval of data while utilizing memory more effectively.

1. Understanding the Concept: A circular queue is a type of data structure that uses a fixed-size buffer in a circular fashion. When one element is processed, the next element is accessed in a circular manner rather than a linear one, which prevents wastage of space.

2. Comparison with Other Options:

   • Rectangle Buffer: This is not a standard term used in data structures.
   • Square Buffer: Similar to the rectangle buffer, this term is also not recognized in the context of circular queues.
   • Curve Buffer: This term might suggest a different kind of data structure but is not commonly associated with queues.

By using a circular mechanism, the ring buffer is particularly efficient in scenarios such as streaming data, buffering I/O operations, or any application that requires continuous data flow without interruption. The ring buffer keeps track of the start and end positions using two pointers, optimally managing the available space.
