How the Internet Never Loses Your Data (TCP Explained)

What actually happens when a packet vanishes on the internet? 📡⚡

The internet is a chaotic, lossy network of physical wires and fiber optics. Cables get cut, buffers overflow, and millions of packets disappear every single second. Yet your video never crashes and your download never corrupts. Here is the invisible protocol running inside your operating system that makes it possible: TCP.

🔹 Sequence numbering 🔹 3x Duplicate ACKs → Fast Retransmit 🔹 Out-of-order reassembly 🔹 Congestion backoff

If you write software, this is what’s keeping your system alive under the hood. 🛠️
