Difference between GUI and CLI

Any device’s operating system is nothing but an interface between the user and hardware components of that device. The operating system offers a GUI vs CLI user interface to interact with an electronic device. Some operating systems provide GUI and CLI, while others offer only CLI. GUI means a Graphical user interface while CLI means the command line interface. As the name suggests, one has to write commands to perform a certain CLI system task. On the other hand, GUI offers graphics that consist of icons and images that enable users to do a task directly. CLI requires expertise in commands for performing a certain task, while a beginner can operate GUI.

For its working, GUI uses computer graphics. One can click on the icon; drag the object with the help of a mouse. There is no need to remembering commands in this. GUI comes with numerous components. With the help of a textbox editor, one can enter input data in this. A menu offers a list of options to choose from. Buttons enable the user to select a particular option. The checkbox element enables the user to select an option to choose from multiple alternatives. Linux and Windows use a Graphical User Interface. It consists of icons, search boxes, windows, menus, and many other graphical elements.

Command language interpreter, Character User Interface, and console user interface are some different command-line interface names. In this system, first, the user enters the commands and presses enter to execute that command. In this way, the user can interact with the device. It is important to have correct knowledge of syntax to give effective commands. An operating system like UNIX has CLI, While an operating system like Linux and windows have both CLI and GUI.

Multitasking

Multitasking may or may not be involved in the command-line interface. On the other hand, In GUI, one can do multitasking with ease. For example- MS word, chrome has multitasking ability to perform tasks.

Command Line Interface is best for handling complex tasks. One can handle the complex task by writing a few commands, while GUI requires some steps to follow to work.

Resource Handling

Only the keyboard and system are used while interacting; on the other hand, GUI has extra resources to interact with the user.

Performance

Graphical User Interface is slow as compared to the Command Line Interface. It required more time to perform tasks. On the other hand, CLI has better performance. One can script the series of instructions to carry out the task, while GUI does not provide this facility.

Networking

Graphical User Interface connects with another computer remotely to gain access, while on the other hand connecting with CLI is quite difficult. Professionals are required to get access to another electronic device.

Interface

In Command Line Interface, the interface is consistent for all the time. In GUI, the interface changes with the update of the software.

Interaction

There is less colour strain in the eyes in the Command Line Interface. In GUI, the colour strain is more. CLI offers more control over the system through a command-line interface. There are few limitations in GUI in accessing folders and perform a certain task.

Examples- Windows Operating System – MS word- GUI, MS Docs-CLI
