Brief History of DOS [Disk Operating System]

Microsoft Corporation designed and developed DOS for the Disk Operating system and released it on 12th August 1981.

It was an extension of CP/M that allowed computers with less memory capacity and storage than a floppy disk drive to run programs stored on magnetic disks or tapes.

Since then, various versions of DOS and windows have been rolled out in the market with a commercial license and open source license.

MS-DOS 1.0 (1977)

This was the original version of Microsoft’s Disk Operating System (DOS).

It allowed users to run programs from their hard drives and connect to other computers using a modem or serial connectors.

It also included commands such as Copy, Xcopy, Edit, and Rename so that files could be moved around easily on your hard drive without knowing much about it!

MS-DOS 2.0 (1980)

This updated version of MS-DOS added support for high-density floppy disks while still keeping compatibility with old software written for 1. x versions.

However, some features, such as memory management, were removed so that programs could take advantage of the extra space available on newer disks.

The latest versions of DOS improved upon this original version by adding support for hard drives and expanding file management features such as copy, paste and delete operations and context-sensitive help files within applications.

This led to more advanced features like multitasking support being added to newer versions such as Windows 3.1.

It still uses DOS underneath its shell layer. Still, it offered improved performance compared to previous releases since it no longer had any external dependencies apart from end-user input devices such as mice.

5 Important Uses of DOS

  1. The disk operating system (DOS) is the most basic operating system used on personal computers.
  2. DOS comes preinstalled in most operating systems like windows and MAC.
  3. The Disk operating system is an important tool for computer users. It enables you to run programs and read files from your hard disk drives.
  4. The disk operating system controls how files and directories [folders] are stored on your computer’s hard drive and how they are retrieved when needed.
  5. The simple commands make navigating through files, folders, and directories easy without using a mouse.
