Protocol

Communication Protocols You Need to Know Protocols are the rules that let devices talk. They describe how data is packaged, when to send it, how to confirm it arrived, and how to keep it safe. Without clear protocols, a web page, an app, or a smart device would fail to cooperate. What is a protocol? A protocol is a formal agreement. It defines how to start a conversation, what to send, how to acknowledge receipt, and what to do when errors occur. It also sets limits on message size and timing, so conversations stay orderly. ...

Communication Protocols: A Practical Guide Communication protocols are the rules that let devices and apps talk to each other. They decide how data is formatted, sent, and understood. A clear protocol story helps avoid miscommunication, delays, and errors in any project. A practical view uses layers. Think of transport (how data moves), the application layer (what the data means), and the encoding used to translate information into bytes. Most systems reuse existing protocols instead of building from scratch. This saves time and makes integration easier. ...

Communication Protocols: From HTTP to MQTT Communication protocols guide how data travels between devices, apps, and servers. HTTP powers the web with a clear request–response flow. MQTT, often used in IoT, favors small messages, low bandwidth, and fast delivery. Both move information, but they do so with different rules and trade-offs. This post explains the basics and helps you choose wisely. Understanding the basics HTTP is built around requests, responses, and stateless messages. A client asks a server for content using methods like GET or POST. MQTT uses a broker and topics: clients publish messages and subscribe to topics to receive updates. This setup fits devices that must stay connected even on limited networks. ...
