Computer Networks LLM Wiki
LLM Wiki — Karpathy Paradigm
One concept, one entry. Relationships expressed as[[wikilinks]].
Structured, navigable, iteratively maintainable.
This wiki was automatically distilled from 1,590 lecture slides across nine chapters of Computer Networks (8th ed.) by Xie Xiren, with course materials generously provided by Associate Professor Yang Xingguang (杨星光).

LLM Wiki Maintenance Principles
- Atomicity — one concept per page, ≤ 200 lines for concept entries
- Link-driven — all mentioned concepts marked with
[[]] - Source-traceable — every entry has a
source:frontmatter field - Version-controlled — Git history records every update
- LLM-iterable — any entry can be handed to an LLM to extend
