Microprocessor-controlled Devices
Overview
A washing machine that starts itself while you are out, a fridge that reorders milk, a car that brakes for a red light on its own: tiny microprocessors hidden inside everyday devices now monitor and control the world around us. They free up our time and make machines smarter, but the same convenience can make us less active, more dependent and more exposed to hackers. Weighing those good and bad effects is exactly the kind of balanced judgement Cambridge wants you to make.
In this lesson you will explore the positive and negative effects of microprocessor-controlled and smart devices in two settings: the home, where they change our lifestyle, leisure time, physical fitness, social interaction and data security, and transport, where they monitor traffic and power autonomous vehicles. You will learn how a device senses, decides and acts, and how to argue both sides of each effect clearly.
