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 — 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.

4 — Network Devices

What NICs, repeaters, hubs, bridges, switches, routers, gateways, firewalls, load balancers, and reverse proxies each actually do, and where each sits in a real network path.

4 — Routing Protocols

RIP, OSPF, and BGP as routing protocols at different scales, plus ECMP and how routing actually holds the internet together.
