Portable Operating System Interface: developed under the
IEEE, a set of
standard operating system interfaces based on the
UNIX operating system. The need for
standardization arose because
enterprises using
computers wanted to be able to
develop programs that could be used the
computer systems of different
manufacturers without having to be re
coded.
UNIX was selected as the basis for a
standard system interface partly because it was manufacturer-neutral.
