1. What are IoT SDKs and Frameworks?

1.1 IoT SDK (Software Development Kit)

An IoT SDK is a collection of software libraries, tools, and documentation that allows developers to build IoT applications efficiently. These SDKs help in connecting devices, managing communication, and integrating cloud services.

Key Features of IoT SDKs:
✅ APIs for device communication (MQTT, HTTP, WebSockets)
✅ Data processing & analytics
✅ Security & encryption tools
✅ Cloud integration (AWS, Azure, Google Cloud, etc.)
✅ Support for multiple programming languages (Python, C, Java, JavaScript, etc.)

1.2 IoT Frameworks

An IoT framework is a structured environment that provides pre-built functionalities for rapid IoT development. These frameworks help manage device connectivity, data flow, analytics, and automation.

Key Features of IoT Frameworks:
✅ Device interoperability (Handles multiple device types)
✅ Cloud-based or Edge processing
✅ Security protocols (TLS, AES encryption)
✅ Integration with AI & Big Data

2. Importance of SDKs and Frameworks in IoT Development

🔹 Faster Development: Pre-built APIs and libraries reduce development time.
🔹 Scalability: Helps in managing thousands to millions of IoT devices.
🔹 Security: In-built security measures (authentication, encryption).
🔹 Multi-Platform Support: Works across embedded systems, mobile apps, and cloud platforms.
🔹 Data Analytics: Supports real-time monitoring, processing, and storage.
