embedded system
Purpose-built computing component
An embedded system is a computer built into a larger device to perform a dedicated function.
Unlike general-purpose computers, embedded systems run specific tasks: the controller in a microwave, the firmware in a car's antilock brakes, the processor in a smart thermostat.
They typically operate with minimal user interface and limited resources, optimized for reliability and efficiency rather than flexibility.
