Lesson plan ကွန်ရက်အခြေခံ / Network foundations 01. Why networks exist Learn: Explain clients, servers, shared resources and LAN versus WAN using a small school example. Demonstration: Draw a PC requesting a file from a server. Practice: Label clients, service and network boundary on a diagram. 02. Network devices and their roles Learn: Distinguish switch, router, access point, modem/ONT and firewall; note combined home devices. Demonstration: Trace a device path from laptop to Internet in a diagram. Practice: Choose devices for a fictional three-PC office. 03. Packets, frames and encapsulation Learn: Introduce data broken into units; separate link delivery from end-to-end addressing. Demonstration: Animate a message through a simple layered envelope drawing. Practice: Arrange application, transport, network and link labels in order. 04. OSI and TCP/IP as troubleshooting maps Learn: Teach layer purpose without rote-only memorisation; map cable, address and application problems. Demonstration: Place three simple faults on a layer diagram. Practice: Explain one problem at physical, network and application levels. 05. Build the lab workspace Learn: Introduce simulator controls, saving projects, lab-only addressing and recovery copies. Demonstration: Build and save two connected hosts in an approved simulator. Practice: Reopen the saved project and identify each device. ချိတ်ဆက်မှုနှင့် Address / Links and addresses 06. Ethernet cables and connectors Learn: Teach copper categories at a conceptual level, RJ45, link indicators, patch panel and cable labels. Demonstration: Inspect labelled patch cables; do not teach live electrical work. Practice: Match sample cable types to a short office scenario. 07. Switching and MAC addresses Learn: Explain MAC learning and forwarding within a LAN; broadcast versus unicast. Demonstration: Observe a switch learning two simulated hosts. Practice: Predict which port should receive a known unicast frame. 08. IPv4 addresses and subnet masks Learn: Teach four octets, host/network idea, mask/prefix and address table. Demonstration: Give two lab hosts valid addresses in one /24. Practice: Complete an addressing table without duplicates. 09. Private/public addresses and default gateway Learn: Explain private ranges, Internet-facing addresses and gateway purpose. Demonstration: Compare same-subnet traffic with a remote-destination path. Practice: Identify which path needs the gateway in four scenarios. 10. Introductory subnetting Learn: Explain CIDR using /24, /25 and /26; count traditional IPv4 subnet host addresses with exceptions deferred. Demonstration: Split one /24 into two /25s and mark network/broadcast addresses. Practice: Calculate ranges for two lab subnets. ကွန်ရက်ဝန်ဆောင်မှု / Network services 11. DHCP lease process Learn: Explain discover, offer, request and acknowledgement; scope, lease and reservations. Demonstration: Let a simulated host receive an address automatically. Practice: Record its address, mask, gateway and DNS settings. 12. DNS names and records Learn: Explain resolver, hostname, A/AAAA and basic cache idea; DNS is not encryption. Demonstration: Compare a name lookup with connecting to an address in a lab example. Practice: Read a supplied lookup result and identify the returned address. 13. TCP, UDP and ports Learn: Explain transport choice, connection versus datagram and service port identifiers. Demonstration: Compare a reliable file-transfer story with a real-time media story. Practice: Match basic services to transport examples. 14. HTTP, HTTPS and everyday services Learn: Explain web requests, TLS purpose and roles of email, file services and time services. Demonstration: Trace a browser request through DNS, connection and application response. Practice: Label what each stage does in a request worksheet. 15. Observe local configuration Learn: Teach read-only ipconfig/Windows settings and how to record evidence without exposing details publicly. Demonstration: Inspect a permitted lab PC and redact identifiers in a sample report. Practice: Produce a private lab configuration sheet. လမ်းကြောင်းနှင့် ခွဲခြားမှု / Routing and segmentation 16. Routing and route tables Learn: Explain next hop, connected routes and longest-prefix idea with a small map. Demonstration: Follow a packet through two simulated subnets. Practice: Choose the next hop from a small route table. 17. NAT and address translation Learn: Explain source translation and port sharing; separate NAT from a complete security policy. Demonstration: Show two lab clients represented by one outward address conceptually. Practice: Draw inside and outside addresses for a home connection. 18. VLANs and broadcast domains Learn: Explain logical segmentation and access ports; distinguish VLAN from physical room. Demonstration: Create two VLANs in a permitted simulator. Practice: Predict which hosts share a broadcast domain. 19. Trunks and inter-VLAN routing Learn: Explain tagged multi-VLAN links and a routing boundary; use vendor commands only in lab. Demonstration: Connect simulated departments through an instructor-tested topology. Practice: Test allowed cross-VLAN reachability and document the path. 20. IPv6 essentials Learn: Introduce hexadecimal notation, prefix, link-local, unicast and compressed zeros. Demonstration: Read and shorten a sample IPv6 address without changing its value. Practice: Recognise equivalent written addresses and a /64 prefix. Wi-Fi နှင့် လုံခြုံရေး / Wireless and security 21. Wi-Fi components and signal Learn: Explain SSID, access point, coverage, interference and shared radio airtime. Demonstration: Map coverage on paper and show a simulated crowded channel situation. Practice: Suggest AP locations for a fictional small classroom. 22. Wireless settings and access protection Learn: Teach WPA2/WPA3 where supported, guest separation and changing approved admin defaults. Demonstration: Use screenshots or an isolated spare router; avoid changing a live office. Practice: Write a guest-network setup checklist. 23. Firewall and least privilege Learn: Explain allow/deny rules, direction and minimum necessary access. Demonstration: Evaluate a small fictional ruleset with source, destination and service. Practice: Write rules allowing one required service and test in lab. 24. VPN and remote access basics Learn: Explain encrypted tunnel, authentication and authorised remote access; distinguish from anonymity guarantees. Demonstration: Draw remote user → VPN endpoint → permitted internal service. Practice: List checks before enabling a fictional remote-work connection. 25. Network documentation and change records Learn: Teach topology, IP inventory, labels, backups and approved change/rollback notes. Demonstration: Improve an incomplete office diagram and addressing sheet. Practice: Document the lab so another learner can reproduce it. ပြဿနာရှာခြင်းနှင့် Project / Troubleshooting and project 26. Troubleshoot with a repeatable method Learn: Teach identify, form theory, test, plan, implement, verify and document. Demonstration: Diagnose an unplugged simulated link without random changes. Practice: Write a concise ticket and one evidence-based hypothesis. 27. Ping, trace and name-resolution tests Learn: Explain what ping/traceroute/nslookup can and cannot establish; ICMP may be filtered. Demonstration: Compare successful gateway ping, failed name lookup and supplied traceroute output. Practice: Choose the next useful test for three failures. 28. Common addressing and service faults Learn: Teach duplicate IP, wrong mask/gateway, missing lease and wrong DNS. Demonstration: Repair three deliberately broken simulator configurations. Practice: Record symptom, root cause, fix and retest for each. 29. Small-office project build Learn: Combine diagram, addressing, segments and services; explain acceptance tests. Demonstration: Show the project requirements and an incomplete topology. Practice: Build the specified office simulation and save evidence. 30. Project fault challenge and review Learn: Assess diagnosis, explanations, documentation and limited changes. Demonstration: Introduce faults in a copy of the learner topology. Practice: Repair three faults and deliver a five-minute network walkthrough. Study approach Watch one lesson, pause to repeat the demonstration, finish the practice task, and explain the idea in your own words. Computer Basics can follow one video per day for 30 days. The other tracks need flexible lab and revision time; 30 videos do not mean 30 days.
