Crumb
/krəm/
noun — “barely enough information to leave a trail.”
Crumb is hacker jargon for a quantity of 2 binary digits—that is, 2 bits. It occupies an awkward but oddly charming place between a single Bit and a nybble, making it larger than the smallest practical unit while still feeling too tiny to deserve serious measurement.
Numerically:
bit
/bit/
noun — “the smallest useful piece of information… and occasionally the smallest useful thought.”
[from the mainstream word and Binary digIT]
Bit is the fundamental unit of information in computing. At the technical level, a bit represents a quantity that can exist in one of two possible states. Those states are commonly expressed as 0 and 1, but may also represent true and false, on and off, yes and no, or any other pair of mutually exclusive outcomes.
