I explained how protocols act as a common language between machines for effective communication. By breaking down the HTTP protocol structure, I demonstrated how clients initiate requests and servers respond accordingly. Additionally, I showcased a practical demo using raw TCP connections to send HTTP messages, highlighting the importance of adhering to protocol specifications for successful communication. I emphasized the significance of understanding and potentially creating custom protocols tailored to specific needs.
