IoT Network Architecture Explained | 4 Layer Architecture |

💡 Topics Covered:

🔹 1. Sensing Layer
The first layer where sensors, actuators, RFID tags, and embedded devices collect real-world data such as temperature, motion, humidity, GPS, etc.

🔹 2. Networking Layer
This layer transfers the data using Wi-Fi, Bluetooth, ZigBee, cellular networks, gateways, and communication protocols.
It ensures secure and reliable data transmission.

🔹 3. Processing Layer
Also called the *Middleware Layer*, it processes and analyses the data using cloud servers, IoT platforms, AI/ML, and databases.

🔹 4. Application Layer
The final layer that delivers user-oriented IoT services such as smart homes, healthcare monitors, agriculture systems, smart cities, industrial monitoring, and more.
