What is a Ring Buffer?

Definition and meaning of Ring Buffer

A ring Buffer is a Data shape that is handled as circular even though it its Implementation is linear. A circular buffer is commonly used as a facts Queue. A circular buffer is a popular manner to put into effect a data circulation due to the fact the Code may be compact.

A ring buffer is likewise known as a round buffer, circular queue or cyclic buffer.

What Does Ring Buffer Mean?

A ring buffer is a commonplace implementation of a queue. It is popular due to the fact round queues are easy to put in force. While a hoop buffer is represented as a circle, inside the underlying code, a ring buffer is linear. A ring buffer exists as a hard and fast-duration Array with pointers: one that represents the head of a queue, and any other that represents the tail. In a queue, elements are added to the tail of the queue in a “FIFO” (first in-first out) style. The first elements of the queue are removed from the top within the order they were introduced. When the pinnacle pointer receives to the cease of the array, it wraps around to the primary detail within the array. Any inFormation inside the buffer is overwritten. The head of the queue is different from the first detail within the actual array and each recommendations circulate as factors are brought and removed.

One disadvantage of a ring buffer is its Constant size. For queues in which elements need to be introduced and removed inside the middle, not just on the begin and give up of a buffer, an implementation as a linked list is the preferred Method.
