Introduction to the Internet of Things (IoT)

Answers and Descriptions:

1. Answer: IoT refers to a network of interconnected devices that communicate and exchange data over the internet to perform tasks.
   Description: IoT connects physical objects (e.g., sensors, appliances) to the internet, enabling automation and remote control, like smart homes or wearables.

2. Answer: IoT is needed to make daily life smarter, more efficient, and automated by enabling device communication and data-driven decisions.
   Description: IoT enhances convenience (e.g., remote home control), improves efficiency (e.g., smart energy systems), and supports innovation in various sectors.

3. Answer: Three IoT applications are smart home devices, remote switches (e.g., controlling a television), and environmental monitoring systems.
   Description: These applications demonstrate IoT’s versatility, from home automation (e.g., smart thermostats) to industrial monitoring (e.g., weather stations).

4. Answer: Enabling technologies for IoT include sensors, microcontrollers, wireless communication (e.g., Wi-Fi, Bluetooth), and cloud computing.
   Description: Sensors collect data, microcontrollers process it, wireless modules enable connectivity, and cloud platforms store/process data for IoT systems.

5. Answer: IoT differs from traditional internet applications by focusing on device-to-device communication and real-time automation, rather than human-centric browsing or services.
   Description: Traditional internet applications (e.g., web browsing) involve user interaction, while IoT enables autonomous device interactions, like a fridge ordering groceries.
