I've seen a few answers in the chat.
I think most of them were right.
The answer is one, one, zero, zero, one.

That's how binary representation works.
You've only been able to type in one of two answers, either 'yes' or 'no', or zero or one, but you've been able to communicate numbers.
As you can probably see now, any number can be represented using binary digits.

Each of these cards represents one binary digit.
When we talk about digital devices these are the digits in 'digital'.
Because there is only two choices (on or off, showing or not showing), the word 'binary' is used.
The 'bi' of binary is the same as the 'bi' in bicycle: it means two.
