Digital Logic & Binary (Deep Dive)
📋 What it is
Binary counts and stores information; combining bits represents numbers, letters, images — everything.
🗣️ Coach says
Binary isn’t just on/off — it’s a counting system. With enough bits (0s and 1s) you can represent any number, and by agreeing on codes, any letter, colour or sound too. That’s how a computer stores a photo or a song: as a huge pattern of bits.
🧠 Memory hook
Bits combine to represent numbers → then letters, colours, sounds. All data is patterns of bits.
😂 Giggle
What did Ohm say when people doubted his law?
"Don't resist — it's a matter of potential over current!"
😲 Whoa!
The letter "A" inside a computer is stored as the binary pattern 01000001 — every letter you type becomes a little string of 0s and 1s.
✅ Quick check: How can 0s and 1s represent a letter or a colour?
Say your answer out loud first — then reveal.
By agreeing on a code — a specific pattern of bits stands for each letter, number or colour.
Binary + a shared code encodes any information.
🧪 Try it! (2 minutes)
Count in binary on your fingers: down=0, up=1. See how few fingers reach surprisingly high numbers.
