At the very core of every smart device, supercomputer, and AI model is a simple concept: logic. Logic gates are the tiny decision-makers inside a computer chip. They take electrical signals and check them against simple rules to decide what happens next.
The Rules of IF and THEN
Computers understand the world in binary—everything is either 'True' (1) or 'False' (0). We build decisions by combining these inputs.
An AND gate only gives a True output if all inputs are True. Think of it like this: IF you have a key AND you turn the key, THEN the car starts.
An OR gate gives a True output if at least one input is True: IF it rains OR you turn on the garden sprinkler, THEN the grass gets wet.
Connecting Simple Rules to Big Brains
By layering millions of these simple logic gates together, we build complex chips. AI models perform millions of mathematical logic steps every second to guess your next word or translate a language.
No matter how smart an AI seems, it is just millions of tiny switches executing basic True/False checks.
