Intorduction to DOS

INTRODUCTION TO DOS 
Disk Operating System (specifically) and disk operating system (generically), most often abbreviated as DOS, refers to an operating system software, used in most computers, which provides the abstraction and management of secondary storage devices and the information on them (e.g., file systems for organizing files of all sorts). Such software is referred to as a diskoperating system since the storage devices it manages are made of rotating platters (such as hard disks or floppy disks). DOS is the medium through
which the user and external devices attached to the system communicate. DOS translates the command issued by the user in the format that is comprehensible by the computer and instructs the computer to function accordingly. It also translates the result and any error message in the format for the user to understand.
