WebApr 2, 2015 · The binary bit, representing one choice, such as Yes/No, is the smallest unit of "information". Therefore, any number of states can be expressed in terms of the number of bits that carry the equivalent amount of information. In the general case, this can be fractional. For example, a 10-state system carries log 2 10 = 3.322 bits of information. WebThis means that every ten bits of width multiplies the number of values that can be represented by about 1000. So, 10 bits allows about a thousand values, 20 bits is about a million values, 30 bits is about a billion, and 32 bits allows over four billion values (because we double the billion two more times for the difference between 30 and 32).
