Network

OSI model

1. Physical
2. Data link -> This is the driver
3. Network -> This is IP layer
4. Transport -> This is TCP/UDP layer
5. Session -> Socket.accept() layer
6. Presentation -> GSON library
7. Application

• TCP on IP Code

  • 3 ways for establish connection
  • 4 ways for closing connection, because both client and server may have data left for sending.

• UDP on IP Code

• epoll (https://www.youtube.com/watch?v=WfJodwornTM) Efficient as it only returned socket/file which have changes.
