- ...MS-Windows
- By the above definition, and a
few others, MS-Windows (3.x or 95) is not an operating
system. Besides, if one tries to find the kernel of these
windowing systems from Microsoft, you find a lot of old
MS-DOS code. Presenting the case that DOS is still the
operating system.

- ...POSIX
- There are some standards organisations which
hope to make money from the publications of their
standards. The IEEE is one of these. Unless you want to
pay for a copy of the standard(s), just knowing that there
is a POSIX standard is probably enough.

- In the mid to late 1980's, many different

prohibitive.

- ...UNICES
- There seems to
be some problems as how one refers to the various versions
of UNIX which are out there. Part of this stems from the
fact that UNIX is all capitals. So, do we have UNIXes?
I've always seen it as UNICES. Use whatever works for you.
