Word Origin & History

while  (n.)
O.E. hwile, acc. of hwil "a space of time," from P.Gmc. *khwilo (cf. O.S. hwil, O.Fris. hwile, O.H.G. hwila, Ger. Weile, Goth. hveila "space of time, while"), originally "rest" (cf. O.N. hvila "bed," hvild "rest"), from PIE *qwi- "rest" (cf. Avestan shaitish "joy," O.Pers. šiyatish "joy," L. quies "rest, repose, quiet," O.C.S. po-koji "rest"). Notion of "period of rest" became in Gmc. "period of time." Now largely superseded by time except in formulaic constructions (e.g. all the while). M.E. sense of "time spent in doing something" now only preserved in worthwhile and phrases such as worth (one's) while. As a conjunction (late O.E.), it represents O.E. þa hwile þe; form whiles is recorded from c.1220; whilst is from c.1375, with excrescent -st as in amongst, amidst (see amid).

while  (v.)
"to cause (time) to pass without dullness, 1635, earlier "to occupy or engage (someone or something) for a period of time" (1606), new formation from while (n.), not considered to be from M.E. hwulen "to have leisure," which is from a Gmc. verb form of while (n.) (cf. Ger. weilen "to stay, linger"). An association with phrases such as Shakespearean beguile the day, L. diem decipere, Fr. tromper le temps "has led to the substitution of WILE v by some modern writers" [OED] (see wile).

Computing Dictionary

while programming
The loop construct found in nearly all procedural languages which executes one or more instructions (the "loop body") repeatedly so long as some condition evaluates to true. In contrast to a repeat loop, the loop body will not be executed at all if the condition is false on entry to the while.
For example, in C, a while loop is written
while () ;
where is any expression and is any statement, including a compound statement within braces "..".
