Binary.
Binary, used to describe a place-value number system, or a number belonging to it, that uses 2 rather than the more common decimal system that uses 10 as its base.
Each digit in a binary number represents a power of 2 and so can only hold a 0 or a 1. The number 2 functions in binary the way 10 functions in decimal numbers: each
power of 2 reached--2 (21), 4 (22), 8 (23), ...--requires an additional digit in binary just as each power of 10 reached--10 (101), 100 (102), 1000 (103), ...--requires an
added digit in the decimal system. The binary numbers 1 through 8 are therefore written:
Decimal Binary
(Base 10) (Base 2)
11
2 10
3 11
4 100
5 101
6 110
7 111
8 1000
Since you can only count to 1 before needing another digit, binary numbers are longer to write out than decimal numbers. Most digital information, such as that stored
on a computer's hard drive, is in binary form.
