An IoT (Internet of Things) architecture consists of several key components that work together to enable seamless communication between devices, networks, and applications. The Device Layer includes sensors, actuators, and embedded hardware that collect data from the environment. The Network Layer is responsible for transmitting this data to other devices or centralized servers using wireless protocols like Wi-Fi, Bluetooth, Zigbee, LoRaWAN, or cellular networks. The Edge Computing Layer processes data locally on edge devices to reduce latency and bandwidth usage, ensuring faster response times for critical applications.

Next, the Cloud Layer stores, manages, and analyzes the vast amounts of data generated by IoT devices. Cloud platforms also provide device management, firmware updates, and integration with analytics and AI tools. The Application Layer represents the user interface where insights and actions are visualized, enabling real-time monitoring and control of IoT systems.

Security, interoperability, and scalability are cross-cutting concerns throughout the IoT architecture, ensuring safe and efficient operation. A solid understanding of these components is crucial for professionals aiming to develop IoT solutions.
