Quick Summary
- Devices (desktop, laptop, tablet, smartphone) each suit different tasks based on power, portability, and screen size.
- Peripherals like keyboards, monitors, printers and external storage extend what a device can do.
- Accessibility peripherals (braille displays, screen readers hardware, haptic devices) let users with disabilities use ICT systems effectively.
- Software splits into three families: productivity (word processors, spreadsheets), specialised (CAD, graphic design), and accessibility (screen readers, voice recognition, magnifiers).
- System settings (display, audio, accessibility features) can be configured without buying new hardware at all.
- Network/security configuration (permissions, protocols, network settings) keeps systems safe and appropriate for their users.
- The exam loves asking you to match a need to a solution and explain why it helps — not just name it.
1. Devices & Peripherals to Meet Specific Needs
Before picking any piece of tech, you always ask the same two questions: What task is this for? and What does this specific user need? A graphic designer, a commuter, and a visually impaired student all need completely different setups — even if they're doing "the same" job of using a computer.
Devices
| Device | Best for | Why |
|---|
| Desktop | Graphic design, video editing | High performance — powerful processor, room for a strong graphics card, easy to upgrade |
| Laptop | Studying, day-to-day business | Portable but still capable — similar functionality to a desktop in a mobile form |
| Tablet | Reading, browsing, simple apps | Lightweight, touch-controlled, great battery life, quick to pick up and use |
| Smartphone | Communication, light tasks | Most portable of all — always in your pocket for email, calls, quick browsing |
💡 Think of it like a spectrum:
As you move from desktop → laptop → tablet → smartphone, you gain portability but lose raw processing power. Every exam question about "which device suits this person" is really asking you to weigh that trade-off.
Practice Question
A freelance video editor works from home but occasionally films and edits short clips on location for clients. Which device would best suit them, and why?
Standard Peripherals
- Keyboard and mouse: essential for desktop setups; ergonomic versions reduce strain during long use.
- Monitors: larger screens boost productivity and cut eye strain — and they're genuinely essential (not just "nice to have") for users with severe visual impairment.
- Printers and scanners: needed for hard copy documents; can also produce enlarged print for users who need it.
- External storage: backup or extra capacity when the main device runs low on space.
Peripherals to Aid Accessibility
This is the section examiners return to again and again — because it forces you to connect a specific disability to a specific device and explain the specific benefit. Memorise these as pairs, not isolated facts.
