Although netty is not a pure JAVA nio, the bottom layer of netty is still based on NiO technology. nio is jdk1 4, which is different from traditional IO, so nio can also be called new io.

First let's think about a question: What is Channel? Channel is an interface abstracted by Netty to read/write network I/O, similar to Channel in NIO. So what are the main features of Channel? Read/Write of Network I/OClient initiates connectionActively close connections, close linksGet the addresses of both sides of the communication ...
