Part 2: Talking Without Words
How people used to send messages across long distances The story of light flashes, drum beats, smoke signals, and Morse code Why using dots and dashes (or 0s and 1s) is so powerful. Let’s Talk in Just Two Choices: On or Off - What is binary, and why do computers love it? How “on” and “off” can mean anything—yes/no, true/false, A/B Why 2 choices are enough to build everything

Part 3: How Electricity Can Carry a Message
What is a circuit? How flipping a switch sends a message Why computers are made of millions of tiny switches.

Part 4: Building Ideas Using Only Switches
What is a logic gate? (Explained without saying “logic gate”) How switches can help us decide things How “AND,” “OR,” and “NOT” control what a computer does.

Part 5: How to Count, Add, and Remember With Just Wires
How computers add numbers using only switches What memory really is: remembering a single bit, then a byte How your computer stores your name, photos, and passwords. How switches can do math with just yes/no What memory means for a machine What bits and bytes really are (without the jargon). What are AND, OR, NOT, and more. How pictures, words, and videos are stored as 0s and 1s.

Part 7: Meet the Heart of the Computer — the CPU

Let’s Find Out How Computers Work

It Never Stops

Once the computer is on, all the parts work together like a team.

  • The brain follows instructions

  • The memory stores quick data

  • The storage holds your files

  • The screen shows what’s happening

  • The mouse and keyboard let you control it

And they all listen to the brain’s orders every second.

 

🧠 Let’s Say You Open a Game

Here’s what happens:

  1. You double-click

  2. The brain sees the click

  3. It asks storage: “Give me the game files”

  4. The files move into RAM

  5. The brain starts running game instructions

  6. The screen draws the game world

  7. The keyboard and mouse send actions

  8. The brain runs more code

  9. Repeat… over and over!

 

💬 What If You Type a Letter?

  1. Keyboard sends the key code

  2. Brain checks what it means

  3. Screen shows the letter

  4. Storage saves it if needed

It feels instant — but it’s millions of tiny steps.

 

🔁 This Keeps Going Until You Shut It Down

The brain never gets tired.
The memory never forgets (as long as power is on).
The storage waits quietly to hold your work.
