Communication Protocols: From Core Internet to Real-Time Apps Protocols are the rules that let devices talk. The core internet grew from simple, reliable delivery with TCP and IP. HTTP then built on top to move documents and data across networks. This setup works well for many tasks, but real-time apps like voice chat or live gaming need something extra: speed and predictability. Real-time needs often favor faster paths, even if that means handling some data loss or reordering in smarter ways. ...

Networking Fundamentals for a Connected World Networks connect devices to share information. At home, in schools, or in offices, you rely on cables, wireless signals, and shared rules to move data from one device to another. A simple goal remains: when you tap a link, a request travels, the server answers, and your screen refreshes. Understanding the basics Think in layers. Each device has a role, and each data packet follows a path from source to destination. In practice, people often use two models to picture this work: the OSI model with seven layers, and the simpler TCP/IP model with four layers. The idea is not to memorize every detail, but to see how ideas fit together: physical links, addresses, transport, and application data. ...

Communication Protocols: From TCP/IP to MQTT Protocols are the rules that let devices talk. This article takes you from the basics of TCP/IP to the lightweight world of MQTT, common in IoT projects. TCP/IP is a broad family of rules for moving data across networks. It splits data into packets, routes them, and can reassemble them at the end. IP handles addressing, while TCP adds reliability with a handshake and acknowledgments. Other rules like UDP offer speed and simplicity, but without delivery guarantees. This balance between reliability and overhead shapes how apps talk online. ...

Communication Protocols You Should Know Communication protocols are the rules that let devices, apps, and services talk to each other. They define how data is formatted, how packets move, and how errors are handled. Understanding these rules helps you design better networks and debug issues faster. Two layers matter most in everyday use: the transport layer and the application layer. Core protocols you likely encounter include TCP/IP, which provides reliable delivery; HTTP and HTTPS for web traffic; DNS to turn names into addresses; and basic file transfers with FTP or SFTP. ...
