Embedded systems are systems designed to perform a specific task by integrating a computer or part of a computer into another machine or system. Since these systems usually have limited resources, they are found in many devices we are exposed to in daily life. For example, mobile phones, white goods, automobiles, medical devices, industrial machines and many other technological products contain embedded systems.

Embedded systems are generally designed for real-time applications. Therefore, an embedded system can quickly process data from the outside world and give instantaneous reactions. For example, an embedded system in a vehicle can manage many tasks in real time, such as speed, fuel consumption, safety systems and engine performance, by constantly monitoring data from sensors.

Embedded systems are often designed using microprocessors or microcontrollers. Such devices generally have advantages such as low power consumption, small size and low cost. These features enable embedded systems to be used in many different areas.
