Windows is a collection of OS's and you can't really lump them together. XP has the NTFS filesystem which has rather powerful file permission capabilities. You can use a FAT filesystem with XP but Microsoft recommends ntfs. In my mind the glaring difference between Windows/Unix is that Unix is multi-user. Diff number 2 would be the XP GUI shell (explorer). Internally, unix has a monolithic kernel while XP has a microkernel (more or less). (Linux is also monolithic and this was the subject of a flamewar between Tovalds and Tennenbaum. Please remember our rules and do not start a flame war here. The thread will be quickly closed should that happen.) And a final large difference is the windows registry concept.
Your diagram does not strike me as correct. The shell should be a layer unto itself.
Swapping is moving entire processes into core or back to the swap area. At first Unix could swap but had no paging. After CPU's had MMU's paging became possible. Now unix pages all the the time and rarely swaps as a last resort. Some OS's (and I am thinking of HP-UX in particular) no longer swap at all. This leaves that swap area with a poor name! (Encrypted passwords have been removed from the password file too. Users rarely have home directories in /usr anymore. Unix has evolved a lot...)

pdf2dsc
PDF2DSC(1) Ghostscript Tools PDF2DSC(1)
NAME
pdf2dsc - generate a PostScript page list of a PDF document
SYNOPSIS
pdf2dsc input.pdf [ output.dsc ]
DESCRIPTION
pdf2dsc uses gs(1) to read an Adobe Portable Document Format (PDF) document "input.pdf" and create a PostScript(tm) document "output.dsc"
that conforms to Adobe's Document Structuring Conventions (DSC) requirements.
This new document simply tells Ghostscript to read the PDF file and to display pages one at a time. The generated document can then be
viewed with any PostScript viewer based on Ghostscript, like ghostview(1) on Unix or GSview on Windows, with which the user can browse
through the pages of the PDF document in any order.
If no output file is named on the command line, the name of the output file is that of the input file with any extension removed, followed
by the extension ".dsc".
CAVEATS
The DSC document uses Ghostscript-specific procedures. In addition, the original PDF document must be accessible when the DSC document is
processed.
You need the file "pdf2dsc.ps" (originally by Russell Lang) supplied with Ghostscript since release 3.53.
SEE ALSO
gs(1), ghostview(1)
VERSION
This document was last revised for Ghostscript version 8.63.
