Ring Buffer
A fixed-capacity circular data structure in which read and write positions wrap around the underlying storage.
Data-Structure Context
A ring buffer uses fixed-capacity storage with producer and consumer positions that wrap at the end of the underlying array. Power-of-two capacities can replace a modulo operation with masking, and the contiguous layout is useful for audio frames, network packets, and low-latency telemetry.
Concurrency Boundary
A single-producer/single-consumer ring is much simpler than a multi-producer/multi-consumer implementation. Correctness in the latter requires explicit treatment of memory ordering, publication, ownership, and counter wrap-around.
