# Network Communication Protocols The following article describes the common network protocols used for IoT connectivity. These protocols define how IoT devices transmit data over networks. * **TCP** (Transmission Control Protocol) – A connection-oriented protocol ensuring reliable data delivery. Used in IoT applications where data integrity is essential (e.g., industrial monitoring, remote healthcare). * **UDP** (User Datagram Protocol) – A faster, connectionless protocol without delivery guarantees. Used in real-time applications like IoT sensor updates and video streaming. * **DNS** (Domain Name System) – Translates domain names (e.g., iotdevice.example.com) into IP addresses, allowing IoT devices to communicate with servers or cloud services without needing to remember IP addresses. * **MQTT** (Message Queuing Telemetry Transport) – A lightweight, publish-subscribe messaging protocol optimized for IoT devices with limited power and bandwidth. * **CoAP** (Constrained Application Protocol) – A lightweight alternative to HTTP, designed for constrained IoT devices in low-power networks. * **HTTP/HTTPS** (Hypertext Transfer Protocol) – Used for cloud-connected IoT applications but can be heavy for low-power devices. * **AMQP** (Advanced Message Queuing Protocol) – A robust, message-oriented protocol used in industrial IoT (IIoT) and enterprise applications. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.monogoto.io/advanced-console/network-management/network-communication-protocols.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
