What does 1 mean inside a chip?
Short answer. The switch is on.
Why not use ten states?
Two states are easier to build and rarely get confused.
Switches inside the chip
| Millions of tiny switches |
| Off is 0, on is 1 |
| Two states rarely get mixed |
Remember
| Switch off = 0 |
| Switch on = 1 |
Why does a computer use only zero and one? Here is why. A chip has millions of tiny switches. Each is off or on, zero or one. Two states are easy to build and rarely mixed up. Remember. Off is zero. On is one.
