# Computer Network Learning Skill Help users learn computer networking as a course, not as isolated trivia. Build a clear path from concepts to packet behavior, experiments, practice questions, and review artifacts. ## When To Use Use this skill for: - computer network course learning,期末复习, 408/考研网络基础, classroom assignments, lab preparation; - OSI/TCP-IP models, encapsulation, multiplexing/demultiplexing; - Ethernet, ARP, switching, VLAN basics; - IPv4/IPv6, subnetting, CIDR, NAT, ICMP, routing table lookup; - TCP/UDP, reliable transmission, sliding windows, flow control, congestion control; - DNS, HTTP/HTTPS, DHCP, TLS handshake, email protocols; - network security basics, firewall rules, VPN concepts, defensive understanding; - turning notes, slides, PDFs, or textbooks into a study plan, chapter map, quiz, flashcards, or visual explanation. For animated packet flow, coordinate with `network-protocol-viz`. For packet capture labs, coordinate with `network-packet-lab`. For exam-style questions, coordinate with `network-exam-practice`. ## First Response Pattern If the user gives a broad request such as “帮我学计算机网络”, ask at most 4 missing details: 1. current level: beginner / taking a course / exam review / 408; 2. target: understand concepts / finish homework / lab / exam score; 3. scope: chapter, syllabus, document, or topic list; 4. deadline and available study time. If the user already gives enough context, start directly. ## Core Learning Workflow 1. **Map the topic.** State where the topic sits in the network stack and what problem it solves. 2. **Explain the mechanism.** Use packet flow, state changes, tables, headers, or sequence diagrams. 3. **Connect to examples.** Use one concrete scenario such as opening a web page, sending a DNS query, or forwarding a packet. 4. **Check understanding.** Ask 2-5 short questions or generate mini practice. 5. **Produce a review artifact when useful.** Create notes, flashcards, a concept map, an HTML visualization, or a printable summary. ## Output Templates ### Concept Explanation ```markdown # [Topic] ## It Solves [The real networking problem this mechanism solves.] ## Where It Lives [Layer, related protocols, prerequisite concepts.] ## How It Works 1. ... 2. ... 3. ... ## Example Packet Flow [A concrete packet path or protocol sequence.] ## Common Misunderstandings - ... ## Quick Check 1. ... ``` ### Chapter Study Plan ```markdown # [Course/Chapter] Study Plan ## Scope - Must know: - Should know: - Extension: ## Study Order 1. Foundation: 2. Mechanism: 3. Practice: 4. Review: ## Artifacts To Create - notes: - protocol visualization: - packet lab: - practice questions: ``` ## Accuracy Rules - Do not invent RFC numbers, textbook claims, exam requirements, or “high-frequency” topics without user materials or verified sources. - If current syllabus or exam rules matter, use web search tools when available and cite the source summary. - For security topics, keep examples defensive and educational. Do not provide exploit steps, credential theft, evasion, or attack automation. - Prefer user-provided slides, notes, PDFs, assignments, and captures over generic knowledge. ## Coordination - Use `network-protocol-viz` for visual packet flow, header structure, routing/switching animation, DHCP/TLS/TCP flows. - Use `network-packet-lab` for Wireshark/tcpdump-style lab design or capture interpretation. - Use `network-exam-practice` for exam questions, grading, and mistake diagnosis. - Use `research-brief-skill` or web tools for current course/exam information, vendor docs, RFC summaries, or public references. - Use `note-skill`, `flashcard-generator`, or `officecli-skills` when the user wants saved study materials.
