What are embedded system?How do u make an embedded system?

I need simple description what an embeded system is and what is a diffrence between super computer and embedded systems

A super computer, like your PC is capable of being programmed for many different tasks. An embedded system is a device that uses computer technology to perform one specific task. For example, it would be foolish to hang a PC on a pole at every intersection to drive the traffic lights. Instead they have a metal box with a microprocessor mounted on a small board designed to time the lights and that's all it will do.

How you would make an embedded system would depend on the job you want it to do. You would need a program that supplies the logic burned on Read Only Memory (ROM) and electronic circuitry capable of taking that output and feeding it to the components that do the job such as relays or step motors etc.

An embedded system is a computer system that comes up with so many inbuilt functions to control many devices. Nowadays, we have seen the embedded system in almost every industry including medical, commercial, industrial etc. For making an embedded system you need to write so many programs according to the working of that embedded system.
A supercomputer is a computer which is capable to perform any task on which you are working on your daily basis.
