The essence of network transmission (buffer transmission) determines the important application of serialization and deserialization.

Serialization: Converts an object to a buffer, obj---->buf

Deserialization: Converts the buffer into an object BUF--->obj

Program ape like obj, network transmission like BUF.

The well-known serialization, deserialization tool is Google protocol buffer, in the previous article, we have been contacted. Of course, many companies also have their own serialization and deserialization tools. We know that the nature of network transmission is the transmission of buffer, so, in the network transmission, serialization and deserialization is very common.
