Document Summary
A computer is nothing more than an absence or presence of a charge (what we are calling on and off) But today we are going to build an actual computer. And we are going to do this based on what we know about these gates: and or or not. Put these gates together in a series: called a circuit. Based on this circuit (and if gates are lined up in right way), we are going to be able to do binary arithmetic -making it an electronic calculating. What he is talking about is an actual physical thing: a vacuum tube. We would put vacuum tubes together in a certain way to create electronic calculating device. Must have power through both a and b to power c. If there is not power going in, there is power gong out. 0 comes into a and not gate flips it to power. Once you understand those you can build a computer.
