An embedded system is a combination of computer hardware, software, and mechanical parts (sensors, actuators, etc.) that is designed to perform a specific function, often in real-time.
These systems require a high degree of predictability and reliability; have a variety of requirements that include size, power, safety, security, cost, and regulation; and typically communicate with one another and interact with the physical world via sensors and actuators in a feedback loop.
Embedded systems—such as a microcontroller in a car—are usually not apparent to the user, but are integral for the successful completion of a particular function (such as the control of a braking system or power windows). Embedded systems engineers research, design, develop, test, and troubleshoot embedded systems.
