the term used to specify how a user interacts with an electronic device, in particular with the computer. CLI and GUI are the different types of user interfaces. They mainly differ in the graphics used in the operating system. To perform an operation on the CLI system you need to write a command. On the other hand, GUI users are provided with visual aids (graphics) that include images and icons, which facilitate users in the direct execution of an activity.
CLI systems require experience in commands for the execution of activities, while the GUI does not require experience, it could also be managed by inexperienced users.

Definition of CLI
CLI the acronym used for Command Line Interface, which are conventional interfaces widely used in the 1980s. A command line interface (CLI) allows users to write commands in a terminal or in a console window to communicate with an operating system. a medium in which users respond to a visual prompt by writing a command and receiving a response from the system. Users must type command or train of command to perform an activity. CLIs are more accurate than GUIs, but require command and syntax mastery. Emphasize the cognitive process as a primary task. The appropriate CLI for costly computing where input accuracy is the priority.
Drawbacks of the CLI
- CLI suitable for the user who uses it regularly and can memorize the range of commands and options.
- Mistyping could cause complete chaos.
- The controls can never be intuitive.
- These are suitable for modeling not for interactive graphics.
Definition of GUI
The GUI does expands to interface graphic user . A GUI uses graphics to allow users to communicate with each other with the operating system or application. The GUI provides windows, scroll bars, buttons, wizards, iconic images, other icons to facilitate users. an easy-to-use interface for novice users. intuitive, easy to learn and reduce the cognitive load . Unlike the CLI, GUI users don't have to remember commands, but they do require the recognition and a good one analysis and graphics explorative .
Disadvantages of the GUI
- Lack of precision
- Replication of the analysis and retracing the steps are difficult.
- Not suitable for modeling.
- Difficult to design.
Key differences between CLI and GUI
- CLI allows users to type the manual command to perform the desired activity while GUI users are provided with visual elements to interact with the operating system such as buttons, icons, images, etc.
- easy to perform an activity in the GUI and useful for beginners. On the other hand, the CLI needs experience on commands and syntax.
- GUI systems require mouse and keyboard while CLI requires only one keyboard to operate.
- Greater precision can be achieved in the CLI than in the GUI.
- The GUI has the advantage over flexibility, in which CLI systems are inflexible.
- The GUI consumes more system space while CLI requires less resources and system space.
- The appearance of the CLI cannot be changed. On the contrary, the adjustable GUI aspect.
- The fastest CLI of the GUI.
Both the CLI and the GUI have their advantages and disadvantages and are appropriate based on user needs and use. The graphical user interface offers a greater level of multitasking and greater efficiency, but the command line interface offers more control, precision and repeatability.
