Logic Gates

A logic gate is a device that is used for creating basic logical functions on digital circuits.

Computers need to have a way to change their behavior based on the information that they compute. In a computer, the logic is assembled from fundamental building blocks called "gates."

Logic gates are like the wizards of the computer world, able to conjure up magic from nothing more than a few electrons flowing through a wire. They are tiny switches that can take in inputs and produce outputs based on simple logic rules.

There are three basic types of logic gates: AND gates, OR gates, and NOT gates. An AND gate only produces an output if both of its inputs are true, while an OR gate produces an output if either of its inputs are true. A NOT gate, on the other hand, simply produces the opposite of its input.

But don't be fooled by their simplicity, my dear friend. Logic gates are the building blocks of all digital technology, from the simplest calculator to the most powerful supercomputer. They allow us to process information, make decisions, and create the incredible digital world we live in today.

So the next time you marvel at the power of your smartphone or lose yourself in a virtual reality game, remember that it's all thanks to the humble logic gate, the tiny switch that holds the power to transform our world.

Transistors make logic gates make flip-flops to represent bytes. They take binary inputs and according to their behavior, give out specific binary outputs.

Logic gates carry digital information based on Booleans so any logic circuit can be formed using combinations of just the following two gates and the appropriate connecting wires.

The AND gate combines its inputs and produces a 1 if both of its inputs are 1, otherwise, the output is 0.

The NOT gate has an output that is the reverse of its input.

AND and the NOT gate can also be combined into a single universal gate called the NAND gate (not and).
