GUI – An Interface to Interact with Electronic Devices

A device or a system that allows unrelated entities to interact with one another is known as an interface. The controller is an interface for both you and a television set, the English language is an interface that connects individuals, and the army process is an interface among personnel of various levels, according to this description. In the Java programming language, an interface is a type, exactly like a class. Methods are defined by an interface, just as they are by a class. After discussing what is an interface, let’s move to what is GUI.

What is a Graphical user interface (GUI)?

A graphical user interface is GUI’s full form in the computer is computer software that allows a human to communicate with a computer using symbols, visual metaphors, and pointing devices (GUI). The GUI has replaced previous computing's esoteric and difficult textual interfaces with a more intuitive approach that has made computer usage not only easier to understand, but also more pleasurable and natural. Its use in Apple Inc.'s Macintosh and Microsoft Corporation's Windows operating systems are well-known. 

The graphical user interface (GUI operating system) has become the de facto standard computer interface, and its components have become cultural icons in their own right.

Let's move on to what is the full form of GUI after discussing what is GUI.

GUI Examples

Sketchpad was created in 1962 by Ivan Sutherland at MIT and consisted of a light pen that allowed users to create and edit things in engineering drawings in real-time with synchronised visuals.

Almost every interactive application, including ATMs, self-service checkouts, airline self-ticketing and check-in, video games, cellphones, and computers, uses modern operating systems and graphical user interfaces. For desktop environments, Microsoft Windows, macOS, Ubuntu Unity, and GNOME Shell are among examples of Graphical User Interfaces, as are Android, Apple's iOS, BlackBerry OS, Windows 10 Mobile, Palm OS-WebOS, and Firefox OS for smartphones.

What is the Difference Between GUI and CUI?

User Interfaces are divided into two categories: GUI and CUI. 

The acronyms GUI and CUI stand for Graphical User Interface and Character User Interface, respectively. The distinctions between these two interfaces will be discussed in this article, as well as whether one has benefits over the other.

User Interface: Everything a user can do to engage with a computer is referred to as the user interface. It is the mechanism through which a user and a computer system communicate through the use of input and output devices.

  • Graphical User Interface (GUI): GUI stands for Graphical User Interface. This is a graphic-based user interface in which the user interacts with the computer. Icons, navigation bars, photos, and other graphics are examples of graphics. The visuals may interact with the mouse when using this interface. It has a highly user-friendly interface that does not require any prior knowledge. For example, Windows features a graphical user interface (GUI).

  • Character User Interface (CUI): CUI stands for Character User Interface. This is a user interface in which the user interacts with the computer solely through the keyboard. Any action necessitates the use of a command. CUI was the forerunner to GUI and was found in the majority of early computers. The majority of current computers utilise GUI rather than CUI. CUI, for example, is a feature of MS-DOS.

Types of User Interface

There are four types of user interface, each with its own set of benefits and drawbacks:

  • Menu-driven Interface 

  • Command Line Interface

  • User Interface in Graphics

  • Touchscreen User Interface in Graphics

Menu-driven Interface 

The menu-driven user interface displays a list or menu with a variety of commands or options in the full-screen, pop-up, pull-down, or drop-down modes. 

The Command-Line Interface

Although the command line interface is no longer widely used as a fundamental user interface in mainstream consumer devices, it is nevertheless used in some situations. Users must put suitable commands onto the command line using the Command Line Interface.

User Interface in Graphics

The graphical user interface, or GUI, is the form of interface that most people are familiar with. You engage with all these systems by pointing and clicking on visuals or icons with a mouse, trackpad, or other accessories.

Touchscreen User Interface in Graphics

The touchscreen GUI is quite similar to the normal GUI, except that instead of using a mouse or trackpad, you use your fingers or a stylus to pick icons and conduct operations. Touchscreen interfaces are prevalent on tablets, smartphones, and other mobile devices. The touchscreen user interface has the same advantages and disadvantages as traditional user interfaces, but it also provides a more personal form of connection. Touchscreen interfaces are particularly handy due to the lack of accessories.

Above are the types of the user interfaces.


Graphical user interfaces (GUI) will soon become the standard of user-centric designs in application programming across various software applications. It provides users with the capability to manoeuvre and operate computers and other electronic devices directly by manipulating graphical icons.

FAQs on GUI Full Form

1. What is GUI in computer and what does it do?

The graphical user interface replaces text-based user interfaces, written command labels, and text navigation. It allows consumers to engage with electronic equipment through the use of graphical icons and audio indications like primary notation.

2.Why is a graphical user interface used?

Most commercially popular computer operating systems and software products today feature a graphical user interface. Word processing and web design tools, for example, can use this interface to provide WYSIWYG possibilities.

3. What are the advantages of GUI?

GUI operating systems have the advantage of allowing interaction through clarity and control.

The basic purpose of any graphical user interface is to give enough clarity for people to rapidly engage and interact with it in meaningful ways. This isn't to say that GUIs can't be built to evoke a feeling of mystery and intrigue, but it's necessary to avoid causing confusion.
