DOS
DOS is an acronym for Disk Operating System. It provides file services to the
application programs, along with generic support for video and printing. DOS
does not provide support for specific displays or printers, nor does it provide serĆ
vices for other peripherals. These services are
not
common to all applications
written for the DOS environment. Each application written for a DOS PC must
provide its own drivers for most of the peripherals that the application uses.

The actual DOS only consists of a small number of files, including an I/O interĆ
face and a command interpreter. The DOS environment that is installed in a
typical desktop PC includes a large number of utility programs (for example,
CHKDSK.EXE) which are not required for the actual booting of a DOS PC, but
are supporting application files. Note that these additional files are not loaded
into the PEN*KEY 6000 Series Computer in the default configuration, but are
available in the toolkit if needed by an application.
