Forms: form: bit buckets

form: bit-bucket
Etymology: The noun is derived from bit (“small amount of something; smallest unit of storage in a digital computer, consisting of a binary digit”) + bucket. Bit in this context originally referred to small pieces of paper punched out from paper tape or punch cards (see sense 1), but came to be regarded as the unit of data storage (sense 2).
The verb is derived from the noun.
Senses: examples: text: The lost bits fall into a container called a bit bucket. They are emptied periodically and the collected bits are used for confetti at weddings, parties, and other festive occasions.

text: bit bucket – the term for a routine or circuit that accepts binary signals and produces no output. Bit buckets are used for testing and to stand in for routines or circuits that have not been implemented at that particular point.

text: Inside the computer, every time a byte moves from one component to another the hardware performs a parity check by counting the number of ones. [...] But let's say a power surge or some other line noise is picked up by the computer and the byte is scrambled. [...] The errant byte, having failed the parity test, is unceremoniously dumped into the bit bucket, the computer's wastepaper basket.

text: An alternative is for the automated spacecraft to assume that tracking is always available and to have the spacecraft take its data and return it accepting that some fraction of the time communication will in fact not be available. Science data would then go into the "bit bucket." Since current spacecraft are complex and expensive, the latter solution is rarely used (intentionally!) today.

text: In [John] Watkinson's view, all recording should be done in non-specific "bit buckets," with a computer figuring out what got recorded where and when.

text: Shifting the contents of the register one bit to the right places a zero in the leftmost bit location and discards the rightmost bit. Conversely, a left-shift pads the rightmost bit with a zero and the upper, leftmost bit falls off into the "bit bucket".
