What is Embedded Systems and IoT?
Within Computer Science, which covers algorithms, programming, data, networks, hardware and safe, responsible use of technology, this topic explains Embedded Systems and IoT. Computing topics explain how software, hardware and data work, with diagrams and models that show each step in order.
Check that you can explain Embedded Systems and IoT in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Embedded Systems and IoT helps you design, test and explain programs, websites and systems, from small projects to exam questions.
Embedded Systems and IoT in detail
An embedded system is a small computer built into a device to do a specific task, such as in washing machines, cars, microwave ovens, traffic lights and fitness trackers. It has a microprocessor, memory and inputs and outputs, and often runs a program stored in ROM, with real-time operation.
The Internet of Things (IoT) connects everyday objects with sensors and internet access so that they can collect and exchange data, as in smart thermostats, doorbells, wearable devices and smart cities. Benefits are convenience and efficiency, while concerns include security (weak devices can be hacked), privacy and reliance on networks.
How the interactive helps you understand Embedded Systems and IoT
Watch the network in the interactive. Use any sliders or buttons it offers to change the values and see how the network responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Embedded Systems and IoT.
Real-life uses and examples
- Apply Embedded Systems and IoT when you design a small program, website or spreadsheet.
- Explain Embedded Systems and IoT to someone new to computing by comparing it to a familiar process.
- Trace through a process that uses Embedded Systems and IoT to check what it does step by step.
Common mistakes to avoid
- Testing only the normal case and forgetting the edge cases.
- Using the term without being able to say what the computer actually does.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
