An embedded system is a specialized computer designed to perform dedicated functions within a larger system. Typically integrated into hardware, such as appliances, vehicles, or industrial machines, it combines software and firmware to carry out specific tasks. Unlike general-purpose computers, embedded systems are optimized for efficiency, reliability, and real-time performance, often operating with limited resources. Their applications range from simple devices like microwaves to complex systems in automotive and medical fields, making them integral to modern technology.
