"Why Do Computers Use Binary"

1. Three things I learned from watching this video are that head phones also require binary to work. Headphones use voltage to make sound. If the voltage is high then the head phone will burst pressure out, but if the voltage is low then it will take pressure in producing sound. To tell how much voltage to put in you only use the number 0-9 any number from 0-1 is 0 any number from 1-2 is one and so on.

2. I don't understand how the adder could get the number wrong if it gets to it at the wrong time. Why would the number change? I also don't understand how cutting the range will help the adder get the number correct.

1. One thing I would like to learn more about is how the voltages are produced from a computer.
