Building Complex Decisions
Single gates are like single words - useful but limited. Combined logic circuits are like sentences that express complex ideas. You might need a car alarm that triggers if (Door open OR Window broken) AND Engine off AND NOT(Key in ignition). By connecting gates together, you can build any logical decision. This is exactly how computers work - billions of simple gates making complex decisions!
