Protocol Buffers

Short summary

A beginner-friendly tutorial explaining Protocol Buffers, covering serialization concepts, language-neutral .proto definitions, and the binary wire format encoding. It walks through how protobuf encodes an int32 field with value 25 into just 2 bytes (08 19) by combining field numbers, wire types, and values. The article is not AI-related but provides a clear technical explainer on data serialization.

• •Protocol Buffers serialize structured data into compact binary format from a single .proto definition
• •Wire format combines field number and wire type using (field_number << 3) | wire_type
• •Example: int32 age=25 encodes to just 2 bytes (08 19) vs JSON's 13 bytes
