Explanation : Binary describes a numbering scheme in
which there are only two possible values
for each digit: 0 and I. The term also refers
to any digital encoding/decoding system in
which there are exactly two possible states.
In digital data memory, storage, processing,
and communications, the 0 and I values
are sometimes called "low" and "high,"
respectively. A single binary digit like "0"
or "1" is called a "bit". The word bit is made
up from the words «binary digit".
