Since this is an ever evolving field with advancement in technology, you will find various definitions of embedded systems out there but what stands out from all of them is that, they are electronic systems that contain either a microprocessor or a microcontroller, but we don’t think of them as computers, because the computer is hidden or embedded in the system.
We can therefore define an embedded system as a microcontroller-based, software-driven, real time control system that is independent, or human or network-interactive which operates on diverse physical variables and in diverse environments albeit reliably.
An embedded system has three main components that are embedded into it:
We have several examples of embedded devices that include:
