Features Of Digital Devices
Muhtasari
Not every digital device is right for every job. A graphic designer needs raw processing power and a high-resolution display, while a delivery driver just needs something portable with reliable GPS. Understanding the features that separate one device from another lets you match hardware to purpose, every time.
This topic walks through nine key features, from portability and performance to security and expansion capability. You will learn how to compare devices systematically and justify your choices, a skill that Edexcel tests directly in both Paper 1 and the practical component.
Malengo
- Understand features of digital devices: portability, performance, storage, user interface, connectivity, media support, energy consumption, expansion capability, security features
- Be able to discuss the features of identified digital devices
