IoT connects physical devices over the internet.
Detailed Explanation
The Internet of Things, or IoT, refers to the interconnection of everyday physical objects to the internet. This means that devices such as refrigerators, thermostats, and even cars are not just standalone items but can share data and communicate with one another through the internet. This interconnectivity allows for smarter living environments where devices can cooperate and provide more streamlined functionalities.
Examples & Analogies
Imagine a smart home where your refrigerator can detect when you're running low on milk and automatically order more online. By connecting various devices through the internet, IoT enables this level of convenience.

Devices communicate via:
- Low-power protocols: LoRa, Zigbee, NB-IoT
- Cloud platforms
- Edge computing
Detailed Explanation
IoT devices use specific communication protocols to relay messages effectively and efficiently. Low-power protocols like LoRa (Long Range), Zigbee, and NB-IoT (Narrowband IoT) are designed for long-range communication with minimal energy consumption. Cloud platforms serve as centralized data hubs where devices can send and retrieve information, while edge computing allows data processing closer to where it is generated, reducing latency and bandwidth use.
Examples & Analogies
Think of IoT communication as a neighborhood of homes. Each house (device) talks to each other using short, clear messages (protocols) to save energy and time. Instead of all information going to a distant office (cloud) and then back to them, some discussions are held at the front lawns (edge computing), making it quicker and more efficient.

Applications:
- Smart homes
- Industrial automation
- Wearable health devices
Detailed Explanation
IoT has numerous applications across various domains. In smart homes, devices can be automated for convenience and energy efficiency, allowing users to control their homes remotely. Industrial automation refers to using IoT technologies in factories to improve processes, monitor equipment, and optimize productivity. Wearable health devices, like fitness trackers, gather health data, allowing users to monitor their wellbeing and share this information with health professionals.
Examples & Analogies
Picture an industrial factory equipped with IoT sensors that monitor machine performance in real-time. If a machine is about to fail, the system can alert staff immediately, enabling preventive maintenance and avoiding costly downtime. Similarly, a health smartwatch can notify you of any abnormal heart rate, prompting you to seek medical attention if needed.
