TCP Chat Room

📝 About project

This is a command line chat room, which is based on Transmission Control Protocol (TCP). Here multiple users can connect and chat with each other, and since it follows TCP there will be no loss of data.

💡 What is TCP?
The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. TCP is a connection-oriented, and a connection between client and server is established before data can be sent. The server must be listening (passive open) for connection requests from clients before the connection is established. The main highlighting fetaure of TCP is that is perform Three-way handshake, and only after that we can send messages.

🗂 Libraries used

1. Threading: A thread is a single sequential flow of control within a program. The real excitement surrounding threads is not about a single sequential thread. Rather, it's about the use of multiple threads running at the same time and performing different tasks in a single program.
   We need to run multiple users at a single time, so for that threading module is used.
2. Socket: The Python interface is a straightforward transliteration of the Unix system call and library interface for sockets to Python’s object-oriented style: the socket() function returns a socket object whose methods implement the various socket system calls. Parameter types are somewhat higher-level than in the C interface: as with read() and write() operations on Python files, buffer allocation on receive operations is automatic, and buffer length is implicit on send operations.

3. Now if you use ls command you will all the files present in this directory. Among them file named server.py is the server file and client.py is the client file.
4. To use it first execute the server file like this.

   [+] Please enter you nickname: 

   After that you will see some messages like this
8. Connect with multiple users, by exetuing client.py in multiple terminal and start chating.
