* Attached Support Processor, one of the two early IBM System / 360 programs that replaces the native SPOOL facilities of OS / 360 ; the other was Houston Automatic Spooling Priority ( HASP ).

Originally released for the IBM 6150 RISC workstation, AIX now supports or has supported a wide variety of hardware platforms, including the IBM RS / 6000 series and later IBM POWER and PowerPC-based systems, IBM System i, System / 370 mainframes, PS / 2 personal computers, and the Apple Network Server.

AIX Version 1, introduced in 1986 for the IBM 6150 RT workstation, was based on UNIX System V Releases 1 and 2.

Among other variants, IBM later produced AIX Version 3 ( also known as AIX / 6000 ), based on System V Release 3, for their IBM POWER-based RS / 6000 platform.

Since 1990, AIX has served as the primary operating system for the RS / 6000 series ( later renamed IBM eServer pSeries, then IBM System p, and now IBM Power Systems ).

In 2003, the SCO Group alleged that ( among other infractions ) IBM had misappropriated licensed source code from UNIX System V Release 4 for incorporation into AIX ; SCO subsequently withdrew IBM's license to develop and distribute AIX.

The original AIX ( sometimes called AIX / RT ) was developed for the IBM 6150 RT workstation by IBM in conjunction with Interactive Systems Corporation, who had previously ported UNIX System III to the IBM PC for IBM as PC / IX.

AIX / 370 was released in 1990 with functional equivalence to System V Release 2 and 4. 3BSD as well as IBM enhancements.

* Auxiliary Storage Pool, a group of disk drives in the IBM i ( aka OS / 400 ) operating system

It is currently supported on IBM Power Systems alongside IBM i and Linux.

The first highly ( or tightly ) pipelined x86 implementations, the 486 designs from Intel, AMD, Cyrix, and IBM, supported every instruction that their predecessors did, but achieved maximum efficiency only on a fairly simple x86 subset that was only a little more than a typical RISC instruction set ( i. e. without typical RISC load-store limitations ).

This decline ( in aerobic capacity ) is most likely a consequence of the sedentary lifestyle that is often associated with the symptoms of IBM ( i. e. progressive muscle weakness, decreased mobility, and increased level of fatigue ).

* IBM RPG, a native programming language for IBM's System i servers

However, some older operating systems ( such as OS / VS1 and OS / VS2 SVS ) and even modern ones ( such as IBM i ) are single address space operating systems that run all processes in a single address space composed of virtualized memory.

IBM System i 570 server ( As of 2006 )

The unified product line is called IBM Power Systems and features support for the IBM i ( previously known as i5 / OS or OS / 400 ), AIX and GNU / Linux operating systems.

In 2006, it was again rebranded as the IBM System i. In 2008, almost 20 years after being introduced, the product line was discontinued and replaced by the IBM Power Systems line.

The IBM System i platform extended the System / 38 architecture of an object-based system with an integrated DB2 relational database.

One feature that has contributed to the longevity of the IBM System i platform is its high-level instruction set ( called TIMI for " Technology Independent Machine Interface " by IBM ), which allows application programs to take advantage of advances in hardware and software without recompilation.

* 1981 – The IBM Personal Computer is released.

AIX ( Advanced Interactive eXecutive, pronounced ) is a series of proprietary Unix operating systems developed and sold by IBM for several of its computer platforms.

The AIX family of operating systems debuted in 1986, became the standard operating system for the RS / 6000 series on its launch in 1990, and is still actively developed by IBM.

It is quite conventional in principle in past and present computing machines of the most varied types, e. g. desk multipliers, standard IBM counters, more modern relay machines, the ENIAC " ( Goldstine and von Neumann, 1946 ; p. 98 in Bell and Newell 1971 ).

For a time, memory capacities were often expressed in K, even when M could have been used: The IBM System / 370 Model 158 brochure ( 1972 ) had the following: " Real storage capacity is available in 512K increments ranging from 512K to 2, 048K bytes.

For example, the internal clock frequency of the original IBM PC was 4. 77 MHz, that is, Hz.

In IBM PC compatible computers, the Basic Input / Output System ( BIOS ), also known as the system BIOS or ROM BIOS (), is a de facto standard defining a firmware interface.

The System / 360 architecture was so popular that it dominated the mainframe computer market for decades and left a legacy that is still continued by similar modern computers like the IBM zSeries.

One notable late CPU design that uses clock gating is that of the IBM PowerPC-based Xbox 360.

Printer steganography is a type of steganography produced by color printers, including Brother, Canon, Dell, Epson, HP, IBM, Konica Minolta, Kyocera, Lanier, Lexmark, Ricoh, Toshiba and Xerox brand color laser printers, where tiny yellow dots are added to each page.

In the case of Software development, this moment is generally agreed to be the publication in the 1980s of the specifications for the IBM Personal Computer published by IBM employee Philip Don Estridge.

The Cyrix 6x86 ( codename M1 ) is a sixth-generation, 32-bit 80x86-compatible microprocessor designed by Cyrix and manufactured by IBM and SGS-Thomson.

: The best known family of operating systems named " DOS " is that running on IBM PCs type hardware using Intel x86 CPUs or their compatible cousins from other makers.

This model is recognized as the first database model created by IBM in the 1960s.

Jack Bresenham at IBM is most famous for the invention of 2D drawing primitives, including line and circle drawing, using only fast integer operations such as addition and branch on carry bit.

IBM is designing hardware to process this information.

Extended Binary Coded Decimal Interchange Code ( EBCDIC ) is an 8-bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems.

The Extended Industry Standard Architecture ( in practice almost always shortened to EISA and frequently pronounced " eee-suh ") is a bus standard for IBM PC compatible computers.

A single class-B element is rarely found in practice, though it has been used for driving the loudspeaker in the early IBM Personal Computers with beeps, and it can be used in RF power amplifier where the distortion levels are less important.

Forth is so named because in 1968 " the file holding the interpreter was labeled FOURTH, for 4th ( next ) generation software — but the IBM 1130 operating system restricted file names to 5 characters.
