UNIX System Services (USS)
(IBM formally called it OpenEdtion)
A misspelling of UNICS (UNiplexed Information and Computing
Service). A hardware-independent operating system originally for minicomputers
and now PCs, too. Once described as a catch-all term for many operating systems
that share some features and a common parentage. Unix was developed by AT&T
and owned by USL, which passed from AT&T to Novell at the end of 1992.
Widely promulgated as a standard operating system, but still has not been as
widely accepted as Unix buffs keep expecting it to. After all, it was designed
to provide a program development environment. Unix keeps coming in waves: to
replace mainframes, as a Web server and to replace Windows on the workstation.
Each wave begins with a concept, its shortcomings revealed as it is
implemented, and competitive technologies having time to catch up as the
shortcomings are addressed. IBM had at various times offered eight different
versions of Unix, but showed little real enthusiasm for the subject, until
September 1991 when it suddenly became an ingredient in the flavor of the year
– openness. And IBM AIX1 was born. The IBM-supported OSF has developed an
independent version of Unix. October 1993, control of Unix fell into the hands
of X/Open who trademarked only the capitalized version UNIX. Currently it is
Linux that is receiving the vast majority of Unix attention, both in the
marketplace and by IBM.

In close cooperation with IBM, SHARE is significantly
enhancing its technical program to address IBM's growing emphasis on UNIX
systems technologies (e.g. AIX, Linux, NUMA-Q, Project Monterey, RS/6000). This
inaugural SHARE event, USERblue, will take place February 26-28, 2001, in Long
Beach, California. |
