🧠 It’s Not Alone

The CPU doesn’t do everything itself.

It works with:

• Memory

• Storage

• Input (keyboard, mouse)

• Output (screen, speaker)

• And more

But it’s the one giving the orders.

Like a conductor of an orchestra:

“Memory, give me the number.”
“Screen, show this word.”
“Speaker, play this sound.”

It never multitasks. It just goes one step at a time, really fast.

And each part of the computer waits for its command.

💬 What Happens When You Open a Game?

1. You double-click the icon

2. The CPU reads the instruction

3. It tells memory: “Load the game”

4. It tells the screen: “Show the game menu”

5. It tells the keyboard: “Watch for arrow keys”

All this happens in a blink.

🧠 So What Is the CPU’s Real Job?

• Follow instructions

• Do them quickly

• Make choices

• Keep everyone else in the computer working together

It’s not the biggest part… but it’s the one that runs the show.
