Computer Networks

A book-shaped table of contents for computer networking, from first principles to production systems: Ethernet through IP, TCP/UDP/QUIC, DNS, the HTTP ecosystem, security, cloud/Kubernetes networking, performance engineering, observability/debugging, and distributed-systems networking — cross-linking existing kubernetes/sre/system-design/tech notes instead of duplicating them.

1 — Ethernet

Ethernet framing, MAC addressing, MTU and jumbo frames, and VLANs/trunk ports as the mechanics of a single local network segment.

3 — Switching

Learning switches, CAM tables, broadcast vs. collision domains, and how Spanning Tree Protocol prevents loops.

1 — Why Computer Networks Matter

Why computer networks exist and matter: the evolution of networking, internet architecture, client-server and peer-to-peer models, and how distributed systems and cloud networking build on top of them.
