Binary Format

aid: binary-format
name: Binary Format
description: Binary format refers to data encoding and serialization methods that use binary rather than text representations,
  including formats like Protocol Buffers, MessagePack, Avro, Thrift, CBOR, and others used in APIs and data storage systems
  for efficiency. Binary formats offer significant advantages over text-based formats in terms of size, parsing speed, and
  type safety.
