Structure, Wireframes, Media, Copyright and Prototypes
Design a home page with up to four linked multimedia pages, choose suitable media formats and create a low-fidelity prototype.
How to study National 5 Computing Science
Move from functional requirements to designs and implementation, trace data and code carefully, and support testing and evaluation with evidence.
Core concepts
Concept 1
A site structure shows a home page, up to four linked multimedia pages and needed external links.
Exam cue: Select a format from the required media features, quality and delivery constraints.
Concept 2
Wireframes cover navigation, consistent layout, readability, relative vertical media position and media file formats.
Exam cue: Keep the prototype recognisably derived from the wireframe.
Concept 3
Copyright law applies to reused text, graphics, video and audio.
Concept 4
WAV and MP3 differ in compression, quality and size; JPEG, GIF and PNG differ in compression, animation, transparency and colour depth.
Concept 5
Resolution, colour depth and sampling rate affect quality and file size; compression reduces storage or transfer needs.
Risk pitfalls and guardrails
Treating all copied web content as free to reuse.
Guardrail: Check option route, data type, valid boundary, loop condition, array index, identifier and expected output before committing to the response.
Claiming higher quality always produces a smaller file.
Guardrail: Check option route, data type, valid boundary, loop condition, array index, identifier and expected output before committing to the response.
Designing more than the specified home page plus four linked multimedia pages as required scope.
Guardrail: Check option route, data type, valid boundary, loop condition, array index, identifier and expected output before committing to the response.
Memory anchors
Site structure
A home page links to no more than four multimedia pages plus any necessary external links.
Wireframe consistency
Repeat navigation and visual conventions across pages.
Copyright
Permission or an appropriate licence is needed to reuse protected web content.
WAV versus MP3
WAV usually preserves more audio data; MP3 compression usually reduces file size.
JPEG, GIF and PNG
Compare compression, animation, transparency and colour depth for the intended graphic.
File-size factors
Resolution, colour depth and sampling rate can increase detail, quality and data size.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
