LAN, MAN, WAN & Network Architectures Study Guide: NEB 12 Computer

Seven-session plan

Turn LAN, MAN, WAN and Network Architectures into retrievable knowledge

LAN, MAN and WAN describe network scope and operational context rather than guaranteed speed. Client-server centralizes services and policy, while peer-to-peer lets nodes share resources directly; real systems may combine architectures.

1. Map prerequisites and definitions.
2. Derive or justify the main relation: Compare scope→ownership→media→latency→administration→security and fault model. Choose architecture from service, scale and control requirements.
3. Redraw diagrams from memory.
4. Study this worked checkpoint: A school computer lab is a LAN, campuses across a city may use a metropolitan link, and branches across countries rely on WAN services.
5. Mix conceptual and numerical questions.
6. Complete a timed closed-book set.
7. Retest only the first wrong decision in each answer.

Use contrast tables and error cards

Place easily confused ideas side by side. Write what stays fixed, what changes, the governing equation and the observable consequence. One high-value warning is: Defining network type only by speed, assuming the Internet is one WAN owned by one body, or treating peer-to-peer as automatically insecure.

Use spaced retrieval: ten minutes today, a closed-book test tomorrow and a mixed review after one week. Explain every graph or diagram aloud before using algebra.

NEB answer method

Model → evidence → equation → check

First identify the system and what the question asks. Label the diagram, apparatus or reaction with SI quantities, then state the principle before selecting an equation. Solve symbolically where possible and check units, limiting cases and chemical or physical meaning.

Make the idea concrete in Nepal

Connect the model to a school laboratory, household technology, health, environment, energy or local material. The example should clarify the science rather than merely mention a place. Compare a prediction with an observation and record uncertainty.
