For example, if we want to use an electric iron to press clothes, we must first plug the cord of the iron into the electric socket and then turn on the switch. If electricity is present, the iron will start warming. Once it is adequately warm, we can start pressing the clothes. In the absence of electricity, the iron will remain cold and we will not be able to press the clothes. Hence, we can say that an operating system works like electricity in the iron.
