To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates ...

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs ... can be built using diodes only. However, by adding a transistor ...

“Computers add numbers together using logic gates built out of ... and chained them together so they add 4 digit binary numbers.” Logic gates are fundamental building blocks of digital circuits.

Logic gates come in a variety of flavors. Computer scientists use them to convert two binary inputs into a single ... order to perform the experiment. In addition, expression of the recombinases ...

along with those for two other gates, to produce the first few steps involved in binary addition and subtraction. The team was also able to create logic gates that calculate in sequence.
