What Is DOS?

What is DOS?


Your disk operating system (DOS) performs a number of essential jobs.
These includes:
  1. Controlling the way various application programs, such as word processors, electronic worksheets, database managers, accounting programs, etc., operate with your computer. DOS creates an environment that lets these programs "talks" to your computer and its input and output devices (printers, modems, display screen, keyboard, disk drivers, etc.). Keyboard and program-generated information is read, interpreted by DOS, and transferred to the selected computer device. Data being returned by your computer device. Data being returned by your computer is again translated by DOS into useful information and written to an output device, such as your display screen, printer, or disk.
  2. Providing "housekeeping" and file management utilities that perform useful tasks such as:
  • Disk preparation (formatting, copying, etc.)
  • File operation (creating, displaying, copying, combining, renaming, deleting, etc.)     
      3. Automating repetitive tasks through automatic execution, or batch file which have the extension             .BAT
      4. Controlling the way certain information is displayed on the screen.
      5. Controlling the way your computer interprets certain commands.

Making, Changing, and Removing Directories

You used the DIR (directory) command in Section 3 to display a list of filenames on the screen. You can create and name multiple disk directories on a disk to allow for the subdivision of your files. This feature lets you group common files into separate directories. This is similar to subdividing information into file cabinet drawers and file folders. This is particularly convenient when you use a fixed disk containing hundreds or even thousands of files. Instead of listing all files in one directory, you can list files in smaller, more manageable sub directories. Lock at the following directory commands.
