🦑Understanding the Network Protocol Stack Simplified 🛠️

Networking is the backbone of modern communication, but the variety of protocols can feel overwhelming. Here's a clean breakdown of the Network Protocol Stack, from physical data transmission to application-level interactions:

🟪 Application Layer (L5-L7)
Where user-facing magic happens! Think web browsing, secure communication, and directory services (e.g., HTTP, TLS, DNS).

🟦 Transport Layer (L4)
Handles data delivery, reliable (TCP) or quick (UDP). New protocols like QUIC ensure modern needs are met.

🟥 Network Layer (L3)
Focuses on routing and addressing, whether through IPv4 or IPv6, with security layers like IPsec keeping it safe.

🟩 Data Link Layer (L2)
Close to hardware , responsible for switching, VLANs, and WiFi connectivity.
