2. Definition of IoT What is IoT? Internet of Things (IoT) refers to the network of physical objects (things) embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet. Example: Smart homes, wearables, connected vehicles.

3. History and Growth of the Internet Brief overview of the internet’s evolution: - 1960s: Birth of ARPANET - 1980s: Invention of the World Wide Web - 1990s: Commercialization and global growth - 2000s: Expansion into mobile and wireless networks.

4. History and Growth of IoT Milestones in IoT development: - 1999: IoT term coined by Kevin Ashton - 2010s: Rise of smart devices and IoT platforms - Current: IoT continues to expand into industries like healthcare, agriculture, and smart cities.

5. Application Areas of IoT Key application domains: - Smart Homes: Home automation, security, and energy efficiency - Healthcare: Wearable devices, remote monitoring - Industrial IoT (IIoT): Predictive maintenance, process automation - Agriculture: Smart farming, irrigation management - Smart Cities: Traffic management, waste control.

6. Focus of IoT Focus areas: - Connectivity: Linking devices and systems - Data Collection: Gathering real-time data from sensors - Automation: Enabling autonomous operations and decision-making - Optimization: Improving efficiency and resource management.

7. Characteristics of IoT Key characteristics: - Connectivity: Continuous communication between devices - Scalability: Ability to grow with the number of devices - Intelligence: Smart data processing and analytics - Dynamic Nature: Adaptability to changing environments - Interoperability: Communication between heterogeneous systems.

8. Things in IoT Physical objects or 'Things' in IoT: - Sensors: Collect data from the environment (e.g., temperature, humidity) - Actuators: Perform actions based on data (e.g., open a valve) - Devices: Embedded systems like smart thermostats, fitness trackers.

9. The IoT Stack (Based on Shriram K. Vasudevan) Layers of the IoT Stack: - Perception Layer: Sensors and actuators that collect data - Network Layer: Connects devices and transfers data - Middleware Layer: Processes and manages data, services - Application Layer: Interfaces and applications for end-users - Business Layer: Analyzes data for decision-making and strategy.
