Unit 1 Software and Processing
System software resource allocation, real-time, batch and multi-user processing, utilities, backup and antivirus.
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
System software allocates memory, storage and processing time so applications and users can use hardware safely and efficiently.
Exam cue: Choose a processing mode from response-time and interaction needs.
Concept 2
Real-time, batch and multi-user processing suit different timing, volume and interaction requirements.
Exam cue: Explain what resource the operating system allocates and why.
Concept 3
Utilities maintain, protect and recover systems through scheduling, defragmentation, backup, restore and updated antivirus controls.
Exam cue: Separate preventing data loss from detecting malware and from restoring after an incident.
Risk pitfalls and guardrails
Calling every program system software.
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.
Confusing real-time processing with simply running quickly.
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.
Treating a backup as useful without a tested restore process.
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.
Memory anchors
System software
Software managing hardware resources and supporting applications.
Real-time processing
Processing that responds within the required operational time limit.
Batch processing
Accumulating similar transactions and processing them together.
Multi-user processing
Sharing system resources among several active users.
Utility software
Maintenance or protection software supporting system operation.
Restore
Recovering usable data or system state from a backup.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
