As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR). Electronic gates operate on two nominal voltages, normally 0 V and 5 V, representing the logic 0 ...

a NOR gate, and any other logic you can dream up. Mechanical computing is decidedly old school, but not at these scales. Turns out, you can make logic out of almost anything. Even Minesweeper.

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...
