computer network visualizer

About this app

See networking, don't just read it.

Computer Network Visualizer turns abstract protocols into living animations. Instead of pages of theory, you watch packets move, layers interact, and routers forward data – in real time.

Perfect for students, teachers, and anyone preparing for CCNA, GATE, or networking interviews.

🔥 WHAT MAKES THIS VISUALIZER UNIQUE
1. OSI Layer Visualizer
Tap any of the 7 layers to see its function. Press “Send Packet” and watch a packet travel from Application down to Physical – with color‑coded animations.

2. Packet Flow Simulator
Watch a packet travel from Client → Router → Server. See the journey step by step, just like in real networks.

3. Subnetting Visualizer
Enter any IP address and subnet mask. The app draws the network bits, host bits, and shows usable addresses – instantly.

4. TCP vs UDP Simulation
Run TCP (acknowledgments, retransmissions) and UDP (fast, no handshake) side by side. See why streaming uses UDP and file transfers use TCP.

🎓 WHAT YOU WILL VISUALIZE
How data moves through the OSI and TCP/IP stacks

How IP addresses are split into network and host parts

How routers forward packets using routing tables

How Ethernet switches learn MAC addresses

The difference between reliable (TCP) and fast (UDP) transport

How DNS translates google.com into an IP address

⚡ KEY FEATURES
No internet required – fully offline after download

100% interactive – tap, drag, simulate

Dark tech UI – easy on the eyes for long study sessions

Smooth animations built with Flutter

Perfect for visual learners

📱 WHO IS THIS FOR?
Computer science students

Networking beginners

CCNA / GATE / UGC NET aspirants

Teachers who want to demonstrate networking concepts in class

Self‑learners who struggle with static diagrams

🧠 LEARN BY DOING
Every concept comes with a “try it yourself” simulation. No more memorizing slide decks – you'll see why TCP needs a three‑way handshake, watch a packet fragment, and experience subnetting visually.

🚀 WHY THIS VISUALIZER BEATS TRADITIONAL APPS
