256 is the only 3-digit number that is
zenzizenzizenzic. It is 2 to the 8th power or .
256 is the lowest number that is a product of eight prime factors.
256 is the number of parts in all compositions of 7.[2]
In computing
One
octet (in most cases one
byte) is equal to eight
bits and has 28 or 256 possible values, counting from 0 to 255. The number 256 often appears in
computerapplications (especially on
8-bit systems) such as:
The typical number of different values in each
color channel of a digital color image (256 values for red, 256 values for green, and 256 values for blue used for
24-bit color) (see
color space or
Web colors).
A 256-bit unsigned integer can represent up to 115,792,089,237,316,195,423,570,985,008,687,907,853,269,984,665,640,564,039,457,584,007,913,129,639,936 values.[6]
