Binary Protocol
ELI5 — The Vibe Check
Binary Protocols encode data as raw bytes instead of human-readable text. Protocol Buffers, MessagePack, BSON — they're smaller, faster to parse, and more efficient than JSON or XML. The tradeoff? You can't read them with your eyeballs. You need tools to inspect them.
Real Talk
Binary protocols use compact byte-level encoding for data transmission, reducing payload size and parsing overhead compared to text-based formats (JSON, XML). Examples include Protocol Buffers, MessagePack, CBOR, Avro, and Thrift. They require schema definitions or self-describing formats for interoperability.

"Switching from JSON to protobuf cut our message size by 70%." / "Binary protocols are faster to parse but harder to debug — you need specialized tools."
