Advanced Interactive Executive

Abbreviated AIX. A version of Unix from IBM that runs on its RS/6000 workstations and on minicomputers and mainframes.

Although AIX is based on Unix System V Release 3, it contains many of the features available in System V Release 4, is POSIX-compliant, and meets the Trusted Computer Base (TCB) Level C2 security.

One of the major enhancements of AIX is Visual Systems Management (VSM), a graphical interface into the older Systems Management Interface Tool (SMIT). VSM contains four main elements: Print Manager, Device Manager, Storage Manager, and Users and Groups Manager.
