A graphical user interface (GUI) uses graphics, along with a keyboard and a mouse, to provide an easy-to-use interface to a program. A GUI provides windows, pull-down menus, buttons, scrollbars, iconic images, wizards, other icons, and the mouse to enable users to interact with the operating system or application.

User Interface is the term used for specifying how a user interacts with an electronic device, particularly computer. CLI and GUI are the different kinds of user interfaces. Mainly they differ in the graphics employed in the operating system. To perform an operation on the CLI system one has to write a command. On the other hand, in GUI users provided the visual aids (graphics) that include images and icons, which facilitates users to perform a task directly.

CLI systems require expertise in the commands for performing task whereas GUI doesn’t require expertise, it could be operated by novice users too.

Definition of CLI

CLI is the acronym used for Command Line Interface, which are conventional interfaces extensively used in 1980’s. A command-line interface (CLI) allows users to write commands in a terminal or console window to communicate with an operating system. It is a medium where users respond to a visual prompt by writing a command and receive a response back from the system. Users have to type command or train of command to perform a task. CLI’s are more accurate than GUI’s, but it requires mastery over the commands and syntax. It emphasizes over cognitive processas a primary task. CLI is appropriate for the costly computing where input precision is the priority.

Drawbacks of CLI

CLI is suitable for the user who uses it in a regular basis and can memorize the range of commands and options.Mistyping could result in complete chaos.The commands can never be intuitive.These are suitable for modelling not for the interactive graphics.

Definition of GUI

GUI expands to Graphical User Interface. A GUI uses graphics to allow users to intercommunicate with the operating system or application. GUI provides windows, scrollbars, buttons, wizards, iconic images, other icons to facilitate users. It is an easy-to-use interface for the novice users. It is intuitive, easy to learn and reduces cognitive load. Unlike CLI, GUI users need not to remember commands rather it requires recognition and good exploratory analysis and graphics.

Drawbacks of GUI

Lack of precision.Analysis replication and retracing of steps is hard.Not suitable for modelling.Difficult to design.

Key Differences Between CLI and GUI

CLI enable users to type manual command in order to perform the desired task whereas in GUI users provided visuals to interact with the operating system such as buttons, icons, images etc.It’s easy to perform a task in GUI and is good for beginners. On the other hand, CLI needs expertise over commands and syntax.GUI systems require mouse and keyboard while CLI just require a keyboard to work.Greater precision can be achieved in CLI as compared to GUI.GUI has the advantage over flexibility, where CLI systems are inflexible.GUI consumes more system space while CLI needs lesser system resources and space.CLI appearance could not be changed. In contrast, GUI appearance is adjustable.CLI is faster than GUI.
