A TCP-based Socket Programming Project

• This is a communication system using socket programming techniques.
• It includes a server and clients, which can realize online chatting.
• The server could supports multiple clients. It assigns multiple userThreads to process each connected client.
• And I use Wireshark to capture and analyze the transmitting packets.

About Socket Programming

Sockets provide the communication mechanism between two computers using TCP. A client program creates a socket on its end of the communication and attempts to connect that socket to a server. When the connection is made, the server creates a socket object on its end of the communication. The client and the server can now communicate by writing to and reading from the socket.
