Explained Simply #2: How does a computer think with just ON and OFF?

How does a computer "think" when all it has is ON and OFF? 🤔💡

1️⃣ TINY SWITCHES: inside every chip are billions of tiny switches called transistors. ON means 1, OFF means 0.

2️⃣ GATES: join two switches in a row and you get a logic gate. Only when A AND B are both on does the output turn on. (Other gates — OR, NOT — work the same way.)

3️⃣ MATHS: gates can add numbers in ones and zeros: 1 + 1 = 10 — that's "two" in binary. Billions of gates doing this, billions of times a second, run your apps, photos and games.

Switches, gates, maths — that is all a computer does!
