Standard unit of information entropy
The bit serves as the fundamental unit of information when entropy is calculated using a base-2 logarithm, representing the uncertainty of a binary choice.
Fundamental unit of information
The bit is the basic unit of information defined by information theory, representing the choice between two equally likely possibilities.
coined and formalized as the unit of information
Shannon adopted the term 'bit' (suggested by John Tukey) to represent the basic unit of information in his 1948 paper, quantifying the amount of uncertainty resolved by an observation.
The bit is the fundamental unit of information used in computing and digital communication. The term is a portmanteau derived from the words binary digit.
A bit represents a single logical state with one of two possible values. While these are most commonly expressed as 1 and 0, they can also be represented by other binary pairs such as true/false, yes/no, on/off, or +/-.
