An embedded system is a specialized computing device designed to perform dedicated functions within larger systems. Commonly found in consumer electronics, automotive applications, and industrial machinery, embedded systems integrate hardware and software components to achieve specific tasks efficiently. Examples include microcontrollers in washing machines, sensors in smart home devices, and control systems in vehicles. Their optimized design allows for real-time operation, lower power consumption, and space-saving, making them crucial in the growing world of Internet of Things (IoT) devices.
