Protocol Buffers

Protocol Buffers, or Protobuf, is a method developed by Google for serializing structured data. It allows you to define data formats in a simple way, similar to creating a blueprint for a building. Once defined, Protobuf efficiently converts this data into a compact binary format for storage or transmission. This makes it faster and less resource-intensive than text-based formats like JSON or XML. Protobuf is widely used for communication between services in software applications, ensuring that data can be easily shared and understood across different systems and programming languages.
