AIX Operating System

What is the AIX Operating System?

AIX stands for Advanced Interactive executive. AIX operating system was developed by IBM in 1986. This operating system was developed for RT PC RISC workstations but later the company makes it available for many other types of hardware like PowerPC-based systems, System-370 mainframes, IBM RS/6000 series, and PS-,2 and also for Apple Network servers. This operating system was very efficient and popular as it was certified by the Open Group's UNIX 03 standard.

The first version of the AIX operating system was released in 1986 and the latest version is AIX 7.2. Various architectures that support the AIX operating system are IA-32, x86-64, ARM, PowerPC, and SPARC. The type of Kernel used in this operating system is Monolithic.

Features of the AIX Operating System:

AIX operating system has many useful features. Some of them are discussed below:

• All the versions of oracles are supported by the AIX operating system.
