Digital and Mobile Devices

What the resources cover

The unit follows a clear path from everyday devices to hardware detail. Early items look at what digital devices are used for, who they are for and what to weigh up when buying one. The mind map USES OF DIGITAL DEVICES shows how devices let people communicate at any time and in any place, from text messages to social networking and instant messaging.

Laptops, phones and the personal computer

Several resources focus on hardware. The mind map Chapter 1: Personal Computer covers cases, power supply, and electricity and Ohm's Law. The Laptops mind map looks at display components, compact size and power sources. The quizzes on laptops ask how a laptop CPU compares with a desktop CPU and which devices can be switched off to save battery. The Cell Phones mind map compares two handsets by producer, battery and performance, while the Chapter 8 Review quiz asks about safe app sources and the iOS home button.

Where to begin

1. Start with the flashcard deck Topic 1: Digital devices to learn the uses, audience and buying factors.
2. Read a mind map such as Mobile Phone Features or Types of Devices to see how ideas connect.
3. Take the Digital Devices quiz, which asks what to consider when choosing a device.
4. Move on to the laptop and mobile quizzes, including the A+ 220-1001 mobile devices quiz, once the basics feel secure.

Using quizzes and maps together

Read a map first, then test yourself. If a quiz answer surprises you, go back to the matching map or flashcard deck and look at that branch again. Repeat until the wrong answers become rare. The listed resources mention GCSE ICT, GCSE Computer Science and IT Essentials, so you will find material that suits those courses, as well as A+ style mobile device questions.
