An embedded system is an electronic system usually controlled with a microcomputer, and a linked software program. It operates machines, equipment, vehicles or materials according to specifications.
Embedded systems are often used in clusters to obtain an integrated solution. The electronics of a car or the avionics of an aircraft are common examples. In this case, the objective of the embedded systems is to improve safety and assist the driver or pilot, or even replace them (i.e., autopilot).
