TCP/IP Model Explained: Layers, Protocols, and Data Flow with Real-World Examples

In this video, we dive deep into the TCP/IP model, the backbone of modern internet communication. We explain the four layers of TCP/IP — Application Layer, Transport Layer, Internet Layer, and Network Access Layer — and discuss their protocols, such as HTTP, DNS, TCP, UDP, IPv4, and Ethernet. 🔹 Application Layer Explore how high-level protocols like HTTP, TLS, and DNS enable communication between applications. 🔹 Transport Layer Learn the differences between TCP (reliable communication) and UDP (faster, connectionless communication). 🔹 Internet Layer Understand how IP (Internet Protocol) routes data between devices using IPv4 and IPv6. 🔹 Network Access Layer Discover how data moves over physical media using Ethernet and Wi-Fi. We will also illustrate the full data flow from sending a simple HTTP request to receiving a response, and we will cover key concepts like packet routing, IP addresses, and encryption. 🔔 Don’t forget to like, subscribe, and hit the notification bell for more tech and networking tutorials!
