What is GUI

 A graphical user interface (GUI) is a type of user interface that allows users to communicate with electronic devices using visual indicators.

Graphical User Interface

The graphical user interface, created by the Xerox Palo Alto research lab in the late 1970s and commercially available in Apple's Macintosh and Microsoft's Windows operating systems, was created in response to the inefficiency of early, text-based command-line interfaces for the average user.

The ability to intuitively control computers and other electronic devices by the direct manipulation of graphical symbols such as buttons, scroll bars, windows, tabs, menus, cursors, and the mouse pointing system will become the hallmark of user-centered design in software application programming. Touch is used in a lot of new graphical user interfaces.

How Does a Graphical User Interface Work?

The model–view–controller software pattern distinguishes internal representations of information from the manner in which information is displayed to the user, resulting in a platform where users are shown which functions are feasible rather than having to enter command codes. Users manipulate visual width to interact with details.

Since graphical user interfaces are separate from application functions, the appearance, or "skin," of an operating system or application software can be changed at any time. In addition to graphical user interface elements already present on the operating system, applications usually incorporate their own special graphical user interface display elements. 

The systematic process of creating test cases in order to assess the functionality of the framework and its design elements is known as graphical user interface testing. Graphical user interface testing tools are available under a variety of licenses and are supported by a variety of platforms. They can be manual or automated and are usually introduced by third-party operators. 

Graphical User Interface Examples

Sketchpad was created in 1962 by Ivan Sutherland at MIT and consisted of a light pen that enabled users to construct and manipulate objects in engineering drawings in real-time with organized graphics.

Almost every interactive application, including ATMs, self-service checkouts, airline self-ticketing and check-in, video games, tablets, and desktops, uses modern operating systems and graphical user interfaces. Microsoft Windows, macOS, Ubuntu Unity, and GNOME Shell for desktop environments, and Android, Apple's iOS, and GNOME Shell for mobile environments are just a few examples of common, modern graphical user interfaces.

Advantages of Graphical User Interfaces

The benefit of a graphical user interface is that it is much easier to use for the average citizen. The features of a graphical user interface make use of familiar metaphors, such as drag-and-drop for file transfer, and use familiar icons, such as a trash bin for deleted files, to create an environment in which computer operations are intuitive and easy to master without any prior experience.

Best Programming Language for Graphical User Interfaces

Although there are several different visual programming languages, each with its own set of advantages for creating a graphical user interface, C# or Java may be preferred due to their ability to run GUIs in a browser and as a desktop application at the same time. Python, HTML5/Javascript, and C/C++ are some other choices.

Difference Between Character User Interface and Graphical User Interface

The use of text commands, controlled by a command-line interpreter, to communicate with a computer program is referred to as a character user interface, also known as a command-line user interface or nongraphical user interface. Typically, command-line interfaces are used by software developers and system administrators to configure computers, control computer data, and access program features that are not available through other means.

Character user interfaces, as opposed to graphical user interfaces, embrace automation and scripting and aim to have more granular control and functionality. While the character user interface was the predominant mode of computer operation until the 1980s, most modern electronic devices now have intuitive graphical user interfaces, and the typical user would rarely if ever, have to use one.

Difference Between Web User Interface and Graphical User Interface

The interaction between a user and software running on a web server is referred to as a web user interface, or web-based graphical user interface, in which the user interface is the web browser and the web page it downloads and renders. Drag-and-drop, audio playback, screen drawing, and keyboard access are all possible thanks to technologies like Flash, Java, JavaScript, and Silverlight.

Web graphical user interfaces are platform-independent, do not require installation or separate software creation, are simple to upgrade and manage because they do not rely on the user to deploy updates, provide a vibrant UI experience, and are low cost, requiring only Ethernet or WiFi interface connectivity.
