Cascading Logic Gates: A (Controlled) Electrical Waterfall!

The reason why we built transistor logic gates in Chapter 9 is because we need to connect multiple logic gates (our building blocks) together to build a computer – the output of one logic gate triggers the input of the next. When we connect multiple transistor logic gates, we can perform more complex operations than a single logic gate allows. In fact, we can create a circuit that can do (binary) addition! This is what all modern computers do: math with (binary) numbers! ...
