MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In computer science, a circular buffer, circular queue, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. This structure lends itself easily to buffering data streams. There were early circular buffer implementations in hardware.

Detailed explanation-2: -A ring buffer (also known as a circular buffer or a circular queue) is a buffer data structure that behaves as if it had a circular shape, in which the last element in the buffer is connected to the first element. Like standard buffers, ring buffers typically have a fixed size.

Detailed explanation-3: -A Circular Queue is an extension of the Queue data structure such that the last element of the queue links to the first element. It is known as Ring Buffer, Circular Buffer or Cyclic Buffer.

Detailed explanation-4: -A Circular Queue is a special version of queue where the last element of the queue is connected to the first element of the queue forming a circle. The operations are performed based on FIFO (First In First Out) principle. It is also called ‘Ring Buffer’.

Detailed explanation-5: -A circular queue is an extended version of a linear queue as it follows the First In First Out principle with the exception that it connects the last node of a queue to its first by forming a circular link. Hence, it is also called a Ring Buffer.
