I know it works most of the time with my pc and my smartphone, but yesterday at the dentist a drill didn’t work correctly, so they turned the entire chair and all the appliances connected to it off and on and the drill was working again. Why does this fix so many problems when nothing is changed in the hardware itself?

A computer program is like driving a car through a busy city. As it runs it makes lots of decisions about what way to go based on what is happening around it, where it just came from and where it is headed next. Most of the time the car knows exactly where it is and exactly where it’s going. Sometimes the situation might cause the car to go down a different road, one where it’s never been before. Maybe a sign was pointing the wrong way? Maybe he missed his exit? Maybe there was a traffic jam or maybe he misread a street name? All of a sudden the program is lost aimlessly driving about different places but not really knowing where to go. It might drive around in circles, go somewhere it shouldn’t, go completely off the map or even crash! Turning our program off puts the car back at the start or in another known location and gives it the chance to try again. If the traffic is just right this time, and all the road signs are in the right places, and the car makes all the right decisions , it should get to where it needs to go.
