Meaning – The term AIX stands for Advanced Interactive Executive, or more commonly, “Ain’t UNIX”. AIX is basically an operating system developed by IBM, and is based on UNIX Operating system.
AIX is used primarily for enterprise level tasks and it comes with a robust set of security options such as Kerberos V5 network authentication and dynamic secure tunnel authentication.
It supports IBM’s 64-bit POWER process, but what is really great is that it is backwards compatible with 32-bit applications as well, something that is very rare to see these days.
The simplest way to remember what AIX is that it is not a consumer level operating system. Rather, it is used for server level tasks and the IT experts are the ones who dabble in this platform.
