What is a ring buffer Python?

A ring buffer is a buffer with a fixed size. When it fills up, adding another element overwrites the oldest one that was still being kept. It's particularly useful for the storage of log information and history. There is no direct support in Python for this kind of structure, but it's easy to construct one.

What is ring buffer used for?

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

What is ring buffer in UART?

It is called a ring buffer because data can wrap around back to the beginning, provided there is space. Really it is just implemented as an array but the beginning of the queue does not have to start at the first element of the array, and the end does not necessarily end at the last element in the array.
