3-2-1 Response to "Why Do Computers Use Binary?"

3 New Things Learned:

1. I learned how the volume of the sound changes due to the voltage.
2. I learned that a wire's voltage can change depending on the the computer reads it, how long the wire itself is or if there are surrounding wires that will interfere.
3. Computers can be analog, because they need to exact to be accurate.

2 Things I Don't Understand Well

1. I don't quite understand how the high and low pressure creates sound.
2. The scale of voltage and how it is split up in order to be accurate.

1 Thing I Would Like to Know More About

1. I would like to know why the number two is so important.
