~~The Binary~~ "Binary" means "involving exactly two". Usually this refers to two states, or ~~base-2 counting system is a system of numbers using only 0 and 1.~~ two items. Thus we talk about

For example the number EQN:110101_2

[[[

| !* EQN:2^5 | EQN:2^4 | EQN:2^3 | EQN:2^2 | EQN:2^1 | EQN:2^0 |

| 1 | 1 | 0 | 1 | 0 | 1 |

]]]

represents the number 32 + 16 + 4 + 1 = 53

Because of the simplicity of the binary counting system and normally electromagnetic storage devices * Binary Numbers, where we only have ~~the facility to store information in one of~~ two ~~states i.e. on or off, computers make great use the base-2 counting system.~~ digits ("binary digits" contracts to "bits"),

* "Binary Operation" which is a method for combining two items

* "Binary Relation" which is a relationship involving two sets.
