06.001 What is a "DOS"?
By: Rubywand
"DOS" means "Disk Operating System". A DOS is a collection of machine
language routines and data which lets a computer Read and Write information to/
from disk. A DOS also includes commands, such as SAVE and LOAD, which you can
use to create and access files on disk.
Apple II DOS, Commodore 64 DOS, and the DOS used on PC's are all called
"DOS"; but, they are different systems. Their commands are similar, sometimes
identical, because what users want to do with disks is about the same whatever
the computer. However, the way each DOS arranges and keeps track of data on
disk is very different. You will not, for example, be able to read files from a
C-64 diskette on your Apple II running under DOS 3.3.
