COMPUTER FUNDAMENTALS

Detailed explanation-1: -The MS-DOS operating system and the command shell in the Windows operating system are examples of command-line interfaces. In addition, programming language development platforms such as Python can support command-line interfaces.

Detailed explanation-2: -The MS-DOS operating system is a command-driven interface, single-tasking operating system. MS-DOS allows the user to navigate, open, and otherwise manipulate files on their computer from a command line instead of a GUI like Windows.

Detailed explanation-3: -A disk operating system doesn’t have a graphical user interface (GUI). Its interface is character-based, so users must type commands in the command line to indicate what actions they want. An example of a PC-DOS 2.0 startup screen on an early IBM PC shows the command-line interface.

Detailed explanation-4: -A command line interface (CLI) enables users to type commands in a terminal or console window to interact with an operating system. Users respond to a visual prompt by typing a command on a specified line, and receive a response back from the system.

Detailed explanation-5: -DOS is a Character User Interface (CUI) operating system. This is quite different from today’s GUI (Graphical User Interface) based operating systems. DOS works on commands that are used to manage and control different hardware components and memory of the computer.
