Postscript is more than that actually. It's a way of encoding files.
Postscript files are document files, encoded in a platform independent
manner, similarly to how PDF (Adobe Acrobat) documents are encoded.

For example, most scientific journal articles available on the web are
stored as postscript files. (.ps files) I have downloaded many
gigabytes of these .ps articles (whether preprints or final
publications).

You can print .ps files out if you have a postscript printer, but that
wastes paper if you just want to see what an article is about. So I
commonly use Ghostscript (with it's GUI Ghostview) to view these files.
Ghostscript interpretes the data in these files and outputs to the screen
so you see exactly what would be printed with a postscript printer. Truly
WYSIWYG. And Ghostscript will also allow you to print postscript files
on non-postscript printers. This is valuable since usually only high end
printers have postscript capability. Ghostview can also be used as
the viewer for PS files within your internet browser.

Ghostview (with Ghostscript) is the associated viewer for PS files just
as notepad is associated with TXT files, winword is associated with DOC
files or netscape can be associated with HTML files.

There are other postscript viewers available for download, but I
believe Ghostscript is the most powerful, and spans the most machine
platforms.
