A complete implementation of Client-Server Communication using Python's built-in socket library — covering both TCP and UDP protocols with real-time bidirectional messaging.

This project demonstrates real-time Client-Server Communication using Python sockets. It implements both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) with features like timestamps, uppercase conversion, message counting, and graceful exit handling.

• ✅ TCP Client-Server Communication
• ✅ UDP Client-Server Communication
• ✅ Student Name & Registration Number on startup
• ✅ Timestamp on every message [HH:MM:SS]
• ✅ Messages automatically converted to UPPERCASE
• ✅ Message counter (tracks total messages sent)
• ✅ Type exit to gracefully end the session

python --version   # Make sure Python 3.x is installed

Open two terminals simultaneously:

# Terminal 1 — Run Server FIRST
python tcp_server.py

# Terminal 2 — Run Client SECOND
python tcp_client.py

# Terminal 1 — Run Server FIRST
python udp_server.py

# Terminal 2 — Run Client SECOND
python udp_client.py

⚠️ Always start the Server before the Client!

========================================
        UDP SERVER STARTED
  Student : Niha Hawas
========================================
Listening on 127.0.0.1:12346 ...
Waiting for messages...

[20:24:28] Client [1]: HELLO
  └ UPPERCASE: [NIHA HAWAS | 2312274] CLIENT: HELLO
Your Reply: HI

[20:24:46] Client [2]: HAVE YOU DONE YOUR TASK
  └ UPPERCASE: CLIENT: HAVE YOU DONE YOUR TASK
Your Reply: YES IT IS DONE

✅ UDP Server closed. Total messages handled: 7
