What If the Instructions Say “If…”?

Sometimes programs say things like:

• If the button is pressed, do this

• If the player loses, end the game

• If the number is bigger than 10, show a warning

How does the computer brain handle that?

It uses logic gates — the same AND, OR, and NOT rules we learned before!

🧩 A Real Example

Let’s say a game says:

“If the player has 0 lives, show ‘Game Over.’”

That’s a decision.

So the brain checks the memory:

• How many lives?

• Is it 0?

If YES → show “Game Over”
If NO → keep playing

🔁 These Are Called “If” or “Compare” Instructions

The brain checks two things:

• “Is A equal to B?”

• “Is A bigger than B?”

• “Is this switch ON?”

Then it chooses:

• Do Step A

• Or do Step B

This is how it decides what to do next.

💡 But It’s Still Just Following Rules

The brain isn’t thinking. It’s just checking:

“Which rule matches the current information?”

And then it moves on.
