All guides Fundamentals
What is the Internet of Things? A plain-language definition
A clear definition of the Internet of Things, what makes a device an IoT device, how the pieces fit together, and where the idea stops being useful.
Architecture
IoT architecture: the layers, from perception to application
The layered model used to describe IoT systems: perception, network, edge, platform and application, what each layer does and where the boundaries blur.
Connectivity & protocols
IoT connectivity overview: choosing between Wi-Fi, BLE, Zigbee, Thread, LoRaWAN and cellular
A practical comparison of IoT radio technologies by range, power, bandwidth, topology and cost, with a decision method for picking the right one.
Connectivity & protocols
MQTT explained: the publish-subscribe protocol behind most IoT platforms
How MQTT works: brokers, topics, QoS levels, retained messages, last will, sessions and MQTT 5 features, with guidance on topic design and when to use it.
Security
IoT security fundamentals: threats and defenses
The main ways IoT devices get attacked, from default passwords to insecure updates, and the layered defenses that keep a fleet trustworthy.
Edge computing
Edge computing explained: processing IoT data close to where it is produced
What edge computing means in IoT, why latency, bandwidth, privacy and resilience push computation toward devices, and how to decide what runs where.
