Unit 2 Multimedia Applications
Evaluation of multimedia and interactive features in e-commerce websites, social media and gaming.
How to study for CCEA GCSE Digital Technology
Connect precise digital concepts to scenario evidence, design decisions, testing and evaluation, then rehearse the controlled-practice lifecycle under your centre's current CCEA instructions.
Core concepts
Concept 1
Multimedia applications combine text, images, sound, video, animation and interaction to support a defined user purpose.
Exam cue: Name the feature, its user action and the outcome it supports.
Concept 2
Interactivity can improve engagement and task completion but may increase load time, complexity, distraction or accessibility barriers.
Exam cue: Balance engagement benefits against performance, safety and accessibility costs.
Concept 3
E-commerce, social and gaming features must be evaluated through user need, performance, safety and commercial purpose.
Exam cue: Judge effectiveness against the application's purpose rather than novelty.

Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Ignoring data collection, moderation or transaction trust in an application evaluation.
