Foundations of IoT: Architecture, Protocols, and Paradigms

The Internet of Things (IoT) is transforming how we interact with the physical world, connecting billions of devices across global networks. To work effectively in this rapidly evolving field, you must first understand the underlying architectures and communication protocols that make these connections possible.\n\nThis text-based course provides a comprehensive introduction to IoT paradigms, mapping hardware constraints to network protocols across the OSI model. You will transition from learning basic terminology to understanding how modern edge devices securely communicate with the cloud, preparing you to analyze and design IoT solutions.\n\nWhat you'll learn:\n- Understand foundational IoT terminology, system architectures, and core paradigms.\n- Analyze communication protocols across all layers of the OSI model, including MQTT, CoAP, and lightweight web standards.\n- Evaluate hardware constraints, power management challenges, and sensor integration in smart devices.\n- Explore modern edge computing concepts and their role in reducing latency and bandwidth.\n- Address critical security considerations, including device authentication and data encryption basics.\n\nThe course begins with fundamental definitions and architectural models, establishing a clear framework for how connected devices operate. You will then progress through the communication protocols, hardware realities, and modern security practices that define the current IoT landscape. Designed for beginners, this course requires no prior background in hardware engineering or advanced networking. Begin reading today to build a strong foundation in the world of IoT.
