Embaded systems?
a specialized computer built into a device to perform a specific function, rather than general-purpose computing.
Key points:
• Usually small, efficient, and dedicated to one task.
• Often has real-time requirements.
• Can be found in everyday devices.
Examples:
• Microwave ovens
• Washing machines
• Car engine control units
• Smart thermostats
In short: an embedded system is a computer hidden inside a device to control it.
