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.

2 — Data Communication Basics

The core data-communication metrics — signals, bandwidth, latency, throughput, jitter, packet loss, serialization delay, and propagation delay — that every later performance discussion depends on.

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.
