Message Queueing Telemetry Transport

Message Queueing Telemetry Transport (MQTT) is a lightweight communication protocol used for connecting devices and transmitting data efficiently. Imagine a system where devices like sensors or smart appliances send small messages to a central hub or server over the internet. These messages are organized in queues, ensuring reliable delivery even if some devices momentarily lose connection. MQTT is designed for minimal bandwidth, making it ideal for IoT (Internet of Things) environments where many devices communicate frequently, securely, and with low power consumption, enabling real-time data exchange and control.
