As a bit corresponds to a binary digit, so a ban is a decimal digit.

Although only two values are possible, they are rarely implemented as a single binary digit for efficiency reasons.

As well as allowing for smaller cell sizes, PCM memory could pack in more data by storing more than one binary digit in each cell.

A two-level quantum system can carry at most one qubit, in the same sense a classical binary digit can carry at most one classical bit.

So where a conventional computer would require separate steps for each binary digit, a qubit can compress the computation, processing information faster.

The molecule, a compound of benzene, changes to a different form when it is struck by a photon of ultraviolet light, allowing it to store a binary digit.

The most well known result is probably the Bailey-Borwein-Plouffe formula which can be used to compute any binary digit of pi without computing all the previous digits.

For example, every hexadecimal digit has an equivalent 4 digit binary number.
