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 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.

Let’s Find Out How Computers Work

🧠 A Computer Without Software Is Like a Brain Without Thoughts

You’ve built the body. It has bones (motherboard), muscles (RAM), a heart (CPU)…
But no mind.

That’s where software comes in.

 

🖥️ Step 1: Pick an Operating System

You need a special kind of software that tells the computer what to do.

That’s called the Operating System, or OS.

Popular ones:

  • Windows: Easy and familiar

  • Linux: Free and great for learning

  • macOS: Only works on Apple computers

For Do-It-Yourself builds, Windows or Linux is best.

 

💿 Step 2: Install It with a USB Stick

Here’s how:

  1. Use another computer to download the OS.

  2. Put it on a USB stick using a tool like “Rufus” (ask a parent/mentor).

  3. Plug that USB into your new computer.

  4. Start the computer, and it should ask:

    “Do you want to install Windows/Linux?”

Say yes!

 

💡 What Happens During Setup?

You’ll see questions like:

  • What’s your name?

  • What’s the time zone?

  • Create a password

Then the computer will:

  • Copy files from the USB

  • Set up your desktop and menus

  • Restart itself a few times

After a while… your computer is ready!

 

🧰 Step 3: Add Some Fun Tools

After installing your OS, you can:

  • Add browsers like Chrome or Firefox

  • Download games or apps

  • Set up antivirus protection

  • Connect to Wi-Fi

  • Explore coding tools like Scratch or Python!

This is YOUR computer now. You made it.

 

🎉 Wait… You Built a Computer!

Yes! You:

  • Picked the parts

  • Put them together

  • Started it up

  • Installed the operating system

  • Gave it a brain!

Now you can:

  • Play games

  • Make art

  • Learn programming

  • Build websites

  • Create anything
