Is a ring buffer a queue?

The ring buffer (also known as a circular buffer, circular queue, or cyclic buffer) is a circular software queue. This queue has a first-in-first-out (FIFO) data characteristic. These buffers are quite common and are found in many embedded systems.

What is ring buffer in Circular Queue?

August 2022) 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.

What is the purpose of a ring buffer?

Ring Buffer (or Circular Buffer) is a bounded circular data structure that is used for buffering data between two or more threads.

What happens when ring buffer is full?

If the buffer is full, we know that our capacity is at the maximum. If head is greater-than-or-equal-to the tail , we simply subtract the two values to get our size. If tail is greater than head , we need to offset the difference with max to get the correct size.
