An embedded system is nothing but a computing system which is meant to perform many operations like to access the info , process the info , store the info and also control the info in electronics based systems. In embedded systems, software commonly referred to as firmware is hidden inside an equivalent hardware instead of in another hardware. Basically embedded systems are task specific devices. one among its most vital characteristic is gives the output within the time constraints otherwise you can say they're time bound systems. These embedded systems help to form the work more convenient and accurate. So, we frequently use these embedded systems in simple and sophisticated devices too. We use these embedded systems in our real world for several devices and applications like Calculators, microwave, television remote , home security and neighborhood control systems, etc.
