GUI or CLI? — TechKnowSurge

About this interactive

The OS Interfaces lesson names the two ways people work with an operating system. A graphical user interface, GUI, pronounced "gooey", is what most systems show you today: folder icons that stand for directories, windows you drag and resize, menus you click or tap. Windows has been mainly a GUI since Windows 95, and the Raspberry Pi desktop and an iPhone screen are GUIs too. A command-line interface, CLI, is a console or terminal where you type text commands and the computer answers in text. At the Windows command prompt, dir lists what is in a folder and cd Desktop changes into the Desktop folder; the same commands work in the Raspberry Pi terminal, and the files they show are the same ones you see as icons in the GUI. MS-DOS worked this way, and so does the text interface on a Cisco switch, where you type commands like show ip interface brief. The test is not which device your hands are on. You can move through a list of icons with the arrow keys, or type a search into the Start menu, and still be in a GUI, because you are working with graphics. You are in a CLI when the way you get things done is by typing commands.

What you'll learn

Distinguish a graphical user interface (GUI) from a command-line interface (CLI) by how the user works: with graphics, or by typing text commands
Recognize that using the keyboard does not make an interface a command line

Key terms

Graphical User Interface: A visual interface that allows users to interact with a computer or application through graphical elements such as windows, icons, buttons, and menus rather than text-only commands. Most modern operating systems use a GUI as the primary user interface.
Command Line Interface: A text-based interface where users interact with an operating system or application by typing commands; it offers precise control and scriptability compared to graphical interfaces.
Command Prompt: The Windows command-line interpreter that provides a text-based interface for executing commands, running scripts, and managing the operating system without a graphical interface. CMD is used for tasks such as file management, network diagnostics, and system configuration.
Terminal: An input/output device with a keyboard and screen that sends keystrokes to a mainframe for processing and displays the results, containing no processing unit of its own.
