This diagram shows that computers use two simple states: ON and OFF.

Each state represents a binary digit: ON means 1, and OFF means 0.

Using only these two states makes it easy for computers to store and process data reliably because electronic circuits can easily detect these two conditions.

This is why binary is the language of computers.

Variations - 2 Challenges

[intermediate] Draw a flowchart showing how a computer reads a binary digit from an electrical signal (ON or OFF) and decides if it is 1 or 0.

[advanced] Draw a diagram explaining how multiple binary digits (bits) combine to represent numbers inside a computer.
