Communication Protocols Under the Hood: TCP/IP and Beyond Every time you send an email, browse a site, or stream video, a quiet map of rules guides the journey. Those rules are called protocols, and they sit at different layers of the network. The core family is TCP/IP, a set of conventions that keeps data moving from your device to a distant server and back. TCP/IP is often explained as layers. A common four-layer model helps, though real systems mix these ideas. Link, Internet, Transport, and Application. Link covers the local network and hardware addresses. Internet handles routing and IP addresses. Transport decides how data travels, choosing reliability or speed. Application hosts the actual services you use, such as HTTP for web pages or DNS for names. ...

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. ...

Communication Protocols You Should Know: from TCP/IP to QUIC The Internet runs on a small family of rules. These rules tell machines how to find each other, how to send data, and how to check that it arrived correctly. A solid grasp of TCP, IP, UDP, and newer options like QUIC helps you diagnose slow pages, choose the right service, and design robust apps. A quick map of the main protocols helps here: ...

Communication Protocols: From TCP/IP to QUIC Networks carry our messages, music, and work across oceans and cities. Today, most apps depend on fast and reliable transport. The journey starts with TCP/IP, the backbone of the Internet, and leads to QUIC, a modern protocol that helps pages load quicker and more securely. This article explains what changed and why it matters for everyday use. Foundations: TCP/IP TCP provides a reliable byte stream. It guarantees that data arrives intact, even if packets take different paths. It uses a handshake to open a connection and a mechanism to recover from loss. This reliability is powerful, but it can introduce latency, especially on mobile networks where connections switch between networks. ...
