octave [(ok-tiv)]

An interval between musical notes in which the higher note is six whole tones, or twelve half tones, above the lower. From the standpoint of physics, the higher note has twice the frequency of the lower. Notes that are an octave apart, or a whole number of octaves apart, sound in some ways like the same note and have the same letter for their names.

Word Origin & History

octave 
c.1300, vtaues (pl., from popular O.Fr. form otaves), later reformed, from M.L. octava, from L. octava dies "eighth day," fem. of octavus "eighth," from octo (see eight). Originally "period of eight days after a festival," also "eighth day after a festival" (counting both days, thus if the festival was on a Sunday, the octaves would be the following Sunday). Verse sense of "stanza of eight lines" is from c.1586; musical sense of "note eight diatonic degrees above (or below) a given note" is first recorded 1656, from L. octava (pars) "eighth part."

octet jargon, networking
Eight bits. This term is used in networking, in preference to byte, because some systems use the term "byte" for things that are not 8 bits long.

octet

in chemistry, the eight-electron arrangement in the outer electron shell of the noble-gas atoms. This structure is held responsible for the relative inertness of the noble gases and the chemical behaviour of certain other elements. The chemical elements with atomic numbers close to those of the noble-gas elements tend to combine with other such elements by losing, gaining, or sharing electrons; as a result of these processes their atoms attain the eight-outer-electron configuration of the noble-gas atoms. This observation, published in separate papers (1916) by the German chemist Walther Kossel and the American chemist Gilbert Newton Lewis, is known as the rule of eight, or octet rule, and is used to determine the valence, or combining capacity, of several chemical elements.
