Introduction to Disk Operating System, MS-DOS

NOTE. Though most of the people use MS-Windows, MS-NT or MS Vista that offer intuitive GUI (Graphical User Interface) as against the CLI (Command Line Interface) provided in DOS (Disk Operating System) but this tutorial series “Everything about DOS” is here to educate the students at schools and engineering colleges across India and anywhere else, as well, as they are being taught MS-DOS in practical lectures. I intend to offer this series as a comprehensive online reference tutorial.

Introduction to Disk Operating System (DOS):

Microsoft DOS is a command line user interface first introduced in 1981 for IBM computers and was last updated in 1994 when MS-DOS 6.22 was released. Although MS-DOS is not commonly used today, the command shell used through Microsoft Windows is.

MS DOS is actually a program that performs “filing system” tasks for your computer system. It organizes files and folders just as filing and organizing paper documents and folders in an office.

Being command-line user interface based, DOS feeds, lives and works on the commands that you type in for it to follow. After you type the command, and hit the return key (the ENTER key), MS DOS finds and executes it. It waits for the next command after the execution of one command.
