embedded system

An embedded system is a small computer or computer-like device that is built into a larger machine or device. It is designed to perform a specific task and it usually has a set of instructions, like a computer program, which tells it how to do it. Embedded systems are commonly found in cars, phones, and other everyday items. They allow us to do things like control how the car drives, make phone calls, and open electronic doors.
