What is an embedded system?
In GCSE Computer Science, an embedded system is a specialised computer built into a larger device to perform a dedicated function. Unlike general-purpose computers, embedded systems are designed for specific tasks.
Examples of embedded systems:
Washing machines
Car engine management systems
Traffic lights
Medical devices
Why are embedded systems used?
They are small, energy-efficient, and cost-effective, making them ideal for devices requiring automation.
