Client-Server Demo

Project Overview

A simple TCP-based client-server demonstration: the server listens for connections, sends a greeting message, and cleanly closes the socket; the client connects, receives the message, and terminates—illustrating basic socket lifecycle and data exchange.

Server Implementation

Initializes and binds a socket, then listens for up to 5 connections:

import socket

s = socket.socket()
print("Socket successfully created!")

port = 56789
s.bind(("", port))
print(f"Socket binded to port {port}")
s.listen(5)
print("Socket is listening")

In the main loop, accepts each client, logs its address, sends a thank-you message, and closes the connection:

while True:
    c, addr = s.accept()
    print("Got connection from", addr)
    message = "Thank you for connecting with us"
    c.send(message.encode())
    c.close()

Client Implementation

Creates a socket, connects to the server, receives the greeting, and prints it:

import socket

s = socket.socket()
port = 56789

s.connect(("127.0.0.1", port))
print(s.recv(1024))
s.close()

Demonstrates a single-request lifecycle: connect(), recv(), and close().
