IBM AIX
Unix operating system from IBM
AIX (pronounced ay-eye-EKS) is a series of proprietary Unix operating systems developed and sold by IBM since 1986. The name stands for "Advanced Interactive eXecutive". Current versions are designed to work with Power ISA based server and workstation computers such as IBM's Power line.
Background
Originally released for the IBM RT PC RISC workstation in 1986, AIX has supported a wide range of hardware platforms, including the IBM RS/6000 series and later Power and PowerPC-based systems, IBM System i, System/370 mainframes, PS/2 personal computers, and the Apple Network Server. Currently, it is supported on IBM Power Systems alongside IBM i and Linux.
AIX is based on UNIX System V with 4.3BSD-compatible extensions. It is certified to the UNIX 03 and UNIX V7 specifications of the Single UNIX Specification, beginning with AIX versions 5.3 and 7.2 TL5, respectively. Older versions were certified to the UNIX 95 and UNIX 98 specifications.
AIX was the first operating system to implement a journaling file system. IBM has continuously enhanced the software with features such as processor, disk, and network virtualization, dynamic hardware resource allocation (including fractional processor units), and reliability engineering concepts derived from its mainframe designs.
“IBM AIX” enters the record as unix operating system from IBM. Crown Archives preserves that source wording while asking what Unix, operating and system can confirm, complicate or overturn.
Why this record matters
“IBM AIX” is worth following because a concise public description often conceals a longer documentary argument. Here, Unix, operating and system provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q269856. None of the 3 selected statements returned an explicit reference. The first chronological checks are 1986.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
