Foundations of the Internet of Things (IoT) and Smart Connectivity

The physical world is becoming increasingly connected, transforming how we interact with everyday devices and systems. This course guides you through the foundational concepts of the Internet of Things (IoT), explaining how smart devices sense, communicate, and share data. You will transition from a curious observer to someone who understands the architecture, protocols, and security measures that power modern IoT ecosystems. By reading through clear explanations and structured written scenarios, you will grasp how to plan and configure basic connected networks. What you will learn: • Understand the core terminology, architecture, and evolution of IoT systems • Learn how sensors, actuators, and microcontrollers interact in a smart network • Explore key connectivity protocols including MQTT, CoAP, and wireless standards • Configure basic network topologies and routing concepts for smart devices • Apply security best practices, including encryption and device authentication, to protect IoT networks • Examine edge computing basics and how data is processed before reaching the cloud. You will begin by learning fundamental definitions and the history of connected technology. From there, the course guides you through hardware components, communication protocols, network configuration, and essential security practices through detailed written explanations and practical design exercises. This course is designed for absolute beginners, technology enthusiasts, and aspiring developers who want to understand IoT from the ground up with no prior hardware or programming experience required.
