ASCIIbetical order /as'kee-be'-tU0259.gif-kl or'dr/ adj., n. Used to indicate that data is sorted in ASCII collated order rather than alphabetical order. This lexicon is sorted in something close to ASCIIbetical order, but with case ignored and entries beginning with non-alphabetic characters moved to the end.

For example, an instruction may be said to do several things 'atomically', i.e., all the things are done immediately, and there is no chance of the instruction being half-completed or of another being interspersed. Used esp. to convey that an operation cannot be screwed up by interrupts. "This routine locks the file and increments the file's semaphore atomically." 2. [primarily techspeak] Guaranteed to complete successfully or not at all, usu. refers to database transactions. If an error prevents a partially-performed transaction from proceeding to completion, it must be "backed out," as the database must not be left in an inconsistent state.
Computer usage, in either of the above senses, has none of the connotations that 'atomic' has in mainstream English (i.e. of particles of matter, nuclear explosions etc.).
attoparsec n. About an inch. 'atto-' is the standard SI prefix for multiplication by 10-18. A parsec (parallax-second) is 3.26 light-years; an attoparsec is thus 3.26 × 10-18 light years, or about 3.1 cm (thus, 1 attoparsec/microfortnight equals about 1 inch/sec). This unit is reported to be
