Simple Socket Server #466

This PR introduces a simple socket communication implementation with a server that can handle a single client connection. The implementation demonstrates basic TCP socket programming concepts including server setup, client connection, and echo functionality.

Adds a complete socket server and client implementation in Python
Includes comprehensive documentation with usage instructions
Updates the main repository README to reference the new implementation

This will start the server on `localhost` and listen on a predefined port (usually `localhost:12345` unless configured otherwise).

The documentation incorrectly states the port as 12345, but the actual code uses port 65432. This should be updated to reflect the correct port number.

The server only handles one client connection and exits after that client disconnects. Consider wrapping the accept() call in a loop to handle multiple sequential connections.

The server doesn't handle potential socket exceptions that could occur during recv() operations. Consider adding error handling for better user experience.

Suggested change

data = conn.recv(1024) # Receive data from the connection

if not data:

break

conn.sendall(data) # Echo the received data back to the client

try:

data = conn.recv(1024) # Receive data from the connection

if not data:

break

conn.sendall(data) # Echo the received data back to the client

except (socket.error, ConnectionResetError) as e:

print(f"Socket error occurred: {e}") # Log the error

break
