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 — Common MAANG Networking Questions

Recurring MAANG networking interview questions — why TCP over UDP, HTTP/2 vs HTTP/3, why TLS needs certificates, what happens when you type google.com, and why latency matters.

2 — Production Incidents

DNS outages, BGP leaks, SYN floods, TLS expiration, and network partitions as the production incident patterns worth knowing cold.

4 — Networking Design Interviews

API gateway, CDN, global load balancer, edge computing, and service mesh as the recurring networking system-design interview prompts.

5 — Review & Cheat Sheets

A consolidated review across TCP flags, HTTP status codes, the TLS handshake, DNS resolution, the OSI model, and CIDR — the interview quick-reference for this entire book.
