Computer Network Learning

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.

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.
