Units of information

Comparison of units of information: bit, trit, nat, ban. Quantity of information is the height of bars. Dark green level is the "nat" unit.

Capacity of some standard data storage system or communication channel, used to measure the capacities of other systems and channels.

Two bits of entropy: In the case of two fair coin tosses, the information entropy in bits is the base-2 logarithm of the number of possible outcomes; with two coins there are four possible outcomes, and two bits of entropy. Generally, information entropy is the average amount of information conveyed by an event, when considering all possible outcomes.

Entropy (information theory)

Average level of "information", "surprise", or "uncertainty" inherent to the variable's possible outcomes.

Use of ternary numbers to balance an unknown integer weight from 1 to 40 kg with weights of 1, 3, 9 and 27 kg (4 ternary digits actually gives 34 = 81 possible combinations: −40 to +40, but only the positive values are useful)

Ternary numeral system

A ternary numeral system (also called base 3 or trinary) has three as its base.
