🔍 Why This Matters

One switch is great. But if one switch can only mean “yes” or “no,” how do we get full videos, websites, or games?

The answer: Lots of switches. Millions of them.

🧠 Each Switch Adds More Possibilities

If 1 switch = 2 messages
Then:

• 2 switches = 4 patterns

• 3 switches = 8 patterns

• 8 switches = 256 patterns

That’s how we get letters, colors, music—all from combinations of ON and OFF.

💾 Memory, Logic, and Speed

All of a computer’s work is done by these switches:

• Memory chips store data as ON/OFF patterns

• Logic chips make decisions using switch rules

• CPUs flip switches billions of times per second

These switches are tiny—they’re called transistors. A single chip can have more than a billion transistors.

🔍 Why It Works So Well

Because electricity is fast. And switches are reliable. Together, they let computers:

• Remember things

• Compare things

• Do math

• Show results

All using nothing but electricity and smart circuits.
