Definition - What does Embedded Device mean?
Techopedia explains Embedded Device
Embedded computers in some home and kitchen appliances are able to communicate with each other; for example, some modern refrigerators can notify the user that there are no more eggs through the display in the microwave that the user is currently interacting with. This system has to be especially designed with these functionalities in mind, so embedded devices and computers that are part of the system have to do specific tasks.
These are now also gaining much use in the automotive industry for smart cars, which have computerized engine and climate controls. The avionics in modern airplanes and fighter planes are also embedded systems.
