ELI5: logic gates (xor etc
// explanation
What are logic gates?
Logic gates are tiny electronic switches that make decisions by looking at their inputs and deciding what to output [2]. They're like traffic lights that only turn green when certain conditions are met [3].
What are the basic types?
There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR, and XNOR [2]. AND gate only says "yes" when both inputs say "yes," OR says "yes" if at least one input says "yes," and XOR is like "yes" only when the inputs are different from each other [4].
How do they actually work?
Logic gates are built using transistors—tiny electronic parts that can turn on and off [3]. When you put lots of transistors together in the right way, they create these decision-making gates [3].
Why do we need them?
Logic gates are the building blocks that make computers work, because computers think in yes-and-no answers, and these gates help process those answers super fast [2].
