What is XOR?

XOR is like a special kind of switch that helps things change when they're different.

Imagine you have two light switches, one on your bedroom wall and one on your parents’ door. If only one of them is turned on, the light in the hallway turns on, but if both are on or both are off, the hallway stays dark. That’s XOR at work!

Let's say each switch can be either on (1) or off (0).

• If one is on and the other is off, the result is on (1).
• If both are on or both are off, the result is off (0).

It’s like a game where you want only one person to be playing at a time. If just one kid starts jumping on the bed, the whole house shakes, but if two kids jump together or none do, it's calm and quiet.

XOR helps computers make smart choices by comparing things in this special way!
