1. /aws/ (East Coast), /ay-os/ (West Coast) A PDP-10 instruction that took any memory location and added 1 to it. AOS meant "Add One and do not Skip". Why, you may ask, does the "S" stand for "do not Skip" rather than for "Skip"? Ah, here was a beloved piece of PDP-10 folklore. There were eight such instructions: AOSE added 1 and then skipped the next instruction if the result was Equal to zero; AOSG added 1 and then skipped if the result was Greater than 0; AOSN added 1 and then skipped if the result was Not 0; AOSA added 1 and then skipped Always; and so on. Just plain AOS didn't say when to skip, so it never skipped. For similar reasons, AOJ meant "Add One and do not Jump". Even more bizarre, SKIP meant "do not SKIP"! If you wanted to skip the next instruction, you had to say "SKIPA". Likewise, JUMP meant "do not JUMP"; the unconditional form was JUMPA. However, hackers never did this. By some quirk of the 10's design, the JRST (Jump and ReSTore flag with no flag specified) was actually faster and so was invariably used. Such were the perverse mysteries of assembler programming. 2. /A-O-S/ or /A-os/ A Multics-derived operating system supported at one time by Data General. A spoof of the standard AOS system administrator's manual ("How to Load and Generate your AOS System") was created, issued a part number, and circulated as photocopy folklore; it was called "How to Goad and Levitate your CHAOS System". 3. Algebraic Operating System, in reference to those calculators which use infix operators instead of {postfix notation}. [Jargon File] (1995-11-26)

Data General AOS (an abbreviation for Advanced Operating System) was the name of a family of operating systems for Data General 16-bit Eclipse C, M, and S minicomputers, followed by AOS/VS and AOS/RT32 (1980) and later AOS/VS II (1988) for the 32-bit Eclipse MV line.

(; older form: ) is the Irish name for a supernatural race in Celtic mythology – spelled sìth by the Scots, but pronounced the same – comparable to fairies or elves. They are said to descend from either fallen angels or the Tuatha Dé Danann, meaning the "People of Danu", depending on the Abrahamic or pagan tradition.

Oração aos moços () is a famous speech written by the Brazilian writer Ruy Barbosa in 1920. Barbosa, a famous lawyer, journalist and politician, presents his thoughts on the role of magistrates and lawyers and gives a retrospective on his own life as an example for upcoming generations.

In computing, array of structures (AoS), structure of arrays (SoA) and array of structures of arrays (AoSoA) refer to contrasting ways to arrange a sequence of records in memory, with regard to interleaving, and are of interest in SIMD and SIMT programming.

A collect call in Canada and the United States, known as a reverse charge call in other parts of the English-speaking world, is a telephone call in which the calling party wants to place a call at the called party's expense. In the past, collect calls were only possible as an operator-assisted call, but with the introduction of computer-based telephone dialing equipment, it is now possible to place a collect call without using an operator, which is called automated operator services (AOS) as opposed to Home Country Direct (HCD).
