Intellectual Property, Digital Signatures & Nepal Cyber Law Practice Set: NEB 11 Computer

Worked practice

Build the result from meaning, not memory

Intellectual property protects eligible creative and inventive work under defined rights and limits. A digital signature uses public-key cryptography to support authenticity and integrity; Nepal cyber-law answers must distinguish technical evidence, legal requirements and ethical practice.

The governing relationship is For a signature, hash the document and sign the hash with a private key; verification uses the corresponding public key and trusted certificate context. For law, identify act, evidence, jurisdiction and current authoritative text. Check the convention, geometry or boundary condition before calculation.

Independent practice ladder

1. Define the key physical quantities and give their SI units.
2. Draw and label the relevant wave, ray, mode or energy diagram.
3. Recalculate the worked example after changing one input by a factor of two.
4. Explain the result without equations.
5. Create a Nepal-relevant situation such as a classroom speaker, musical pipe, optical slit or thermal machine.
6. Compare two cases and predict the larger output before calculating.
7. Find and repair one deliberately wrong sign, node or unit.
8. Write a three-mark answer and a five-mark answer.

Answer protocol: diagram → known data → principle → symbolic equation → SI substitution → result → physical check. Calling a scanned handwritten mark a cryptographic digital signature, assuming copyright means no exceptions, or quoting penalties without checking the current official law.

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.
