TCP/IP Model – Step by Step Guide
🌐 TCP/IP Model – Step by Step Guide
⬛ 1. Application Layer
👉 User creates the data. (Example: opening a website or sending a message).
⬛ 2. Transport Layer
👉 Breaks data into Segments and adds TCP/UDP header.
👉 Ensures which app should receive it and keeps the right order.
⬛ 3. Internet Layer
👉 Segments become Packets.
👉 IP header is added with Source & Destination addresses.
👉 Decides the best route for the data.
⬛ 4. Network Access Layer
👉 Packets turn into Frames.
👉 Adds MAC Address + Error Checking for local delivery.
⬛ 5. Physical Layer
👉 Frames are converted into Bits (0s & 1s).
👉 Transmitted through cable (Ethernet) or wireless signals.
📥 On the Receiver Side
Data flows back: Bits → Frame → Packet → Segment → User Data.
👉 This is called Decapsulation.
📤 On the Sender Side
Headers & Trailers are added at each layer.
👉 This is called Encapsulation.
