Miks Protocol Buffers abil andmete serialiseerimine võtab vähem ruumi kui JSON?

Protocol Buffers (protobuf) occupy less space compared to JSON because:

• Binary format: protobuf serializes data into a compact binary format, whereas JSON is a text format with redundant characters (quotes, commas, spaces).
• Absence of repeated keys: in protobuf, the data structure is predefined by a schema, so field names are not stored in each message, unlike JSON where keys are repeated.
• Type optimization: protobuf uses efficient methods for encoding numbers and other types (e.g., varint for integers), reducing size.

In summary, protobuf provides more compact and faster data storage and transmission, which is especially important for systems with limited resources or high load.
