computer logic

It should probably be pointed out that computers should not be seen as implementing pure "binary" logic, because many devices use three states, high, low, and disconnected - the high impedance state. The simplest devices (latch & driver) have an input lines, an output lines, and a control line which enable when the input or output lines are active. The simplest one-bit memory cell has three possible outputs high, low, and disabled. My inclination is to think of computers as using tertiary logic to manage binary logic.
