external communication.

of MS-DOS, Microsoft’s disk operating system. The
MS-DOS operating system contains the instructions
that enable your application program to work
automatically with the hardware.
Your software cannot communicate with your Apex
hardware without instructions from the operating
system. The operating system controls system input
and output and the operation of all disk drives. Think
of a traffic controller managing traffic at the busiest of
intersections, and you’ll have an idea of the role of
your operating system.
