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 — HTTP Fundamentals

The HTTP request lifecycle — methods, status codes, headers, and cookies — as the foundation every later chapter in this Part builds on.

4 — GraphQL

GraphQL's query, mutation, and subscription model, and the performance trade-offs it makes relative to REST.

6 — WebSockets

The WebSocket upgrade handshake and persistent, full-duplex connections that make real-time systems possible over HTTP.
