Contemporary logic circuits use MOSFETs as the elements to build gates, but there are many ways to implement them. Using relays is one of them, and you can literally see how they work.

When pulsed at their inputs, they change their state. To learn how gates work in a circuit, see Boolean logic. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

Most if not all of the standard logic blocks come in an inverted form also such as the NAND gate shown here ... Above is a simple circuit that demonstrates using parenthesis to indicate order ...

A new breakthrough in optical computing could help make computers dramatically faster. A team of scientists from Skoltech in Russia and the University of Wuppertal in Germany has shown that a special ...
