Communication Protocols That Shape the Internet The Internet runs on a stack of rules called protocols. Each layer has a job, from moving bits to naming devices to delivering content securely. These rules are designed to be simple, scalable, and interoperable, which is why billions of devices can work together across many networks. Foundations of Data Transfer At the base are IP and TCP. IP handles addressing and routing, delivering packets between devices. TCP adds reliability with a handshake, sequencing, and error correction so data arrives intact. ...

Network architecture and routing protocols explained Network design shows how devices connect and talk to each other. It helps decide where to place hardware, which links to use, and how to keep data moving even if a part of the system fails. On one end you have a home Wi‑Fi setup; on the other, a global internet connection with many sites. Each layer has goals for speed, reliability, and security. ...
