What is GUI? Main components of GUI

 What is GUI? Graphical user interface (GUI) has become an important part of human-computer interaction. This article from  TipsMake  will explore the components of graphical user interface and its benefits.

What is GUI?

A graphical user interface (GUI) is a type of interface that allows users to interact with a computer or device through images, icons, and other visual elements. Instead of entering written commands as in a command-line interface (CLI), a GUI provides a more user-friendly experience.

What is GUI?

The graphical user interface was created to make using a computer easier and more intuitive. With a GUI, users can perform tasks simply by clicking icons, dragging and dropping objects, and using menus to select options.

How does GUI work?

The graphical user interface works by converting commands into images and icons that the user can recognize and interact with. When the user performs an action, the GUI coordinates these requests and sends them to the system for execution.

When the user clicks the mouse or touches the screen, this signal is recorded and converted into specific actions.

Operating systems that support GUI are very diverse: Windows, macOS and Linux all have their own programming libraries for GUI development, such as WinAPI, Cocoa, GTK+,. In addition, frameworks such as React, Angular, or Vue.js in web development also help build modern graphical interfaces.

History of Graphical User Interface Development

GUIs evolved in the 1960s, but they did not really become popular until the 1980s. During this period, GUIs changed the way users interacted with computers.

Early Stage: From CLI to GUI

Before the GUI, users had to use the command line interface (CLI) to interact with the computer. Everything had to be entered in text, making it difficult for people unfamiliar with programming to use the computer. Realizing this, researchers at Xerox PARC developed the first graphical interface based on icons and windows. The idea quickly gained traction and led to the release of the Macintosh in 1984, a product that featured a user-friendly GUI.

The Explosion of GUIs

In the late 1980s and early 1990s, the development of GUIs increased dramatically with the emergence of Microsoft's Windows operating system. Windows not only provided a better user experience, but also expanded the accessibility of computer technology to a wide range of non-professional users.

Current and future trends

With the advent of mobile devices and tablets, GUI design has changed to accommodate smaller screens and new ways of interacting. The current trend is to optimize the user experience through factors such as sensitivity, responsiveness, and personalization.

Main components of GUI

A graphical user interface consists of many different components, each of which plays an important role in creating the complete user experience. Below are the main components of a GUI.

Windows

A window is a frame that displays information, allowing users to interact with applications. It can be opened, closed, moved, and resized. Each window usually contains other components such as menus and icons, which help users perform necessary operations.

Menu

A menu is a list of options or commands that a user can select to perform different functions within an application. Menus are typically displayed at the top of a window or as a drop-down list when a particular icon is clicked.

Icons

Icons are small images that represent an application, document, or function. Icons help users easily recognize and quickly access resources without having to remember commands.

Widgets

Widgets allow users to perform specific interactive actions such as buttons, dialog boxes, scroll bars, and input fields. 

Buttons

Buttons are elements that a user can click to perform a specific action such as opening a program or sending a command.

Toolbars

A toolbar contains buttons or icons arranged in rows or columns, typically located at the top or side of an application window. 

Scroll Bars

Scroll bars allow users to move content within a window when the content exceeds the display size. Users can drag the scroll bar to view more information easily.

Tab

Tabs are small boxes containing graphical icons that allow users to switch between different content within the same window without opening multiple separate windows.

The Great Benefits of GUI

Graphical user interfaces offer many advantages over traditional interfaces. Here are some of the key benefits that GUIs offer.

1. User-friendly experience: Due to the intuitive icons and images, even people with no prior experience in technology can easily use the GUI. The simplicity in interacting with the GUI saves users time and effort. 
2. Increased Productivity: By organizing and presenting information logically, GUIs help users focus on their tasks without distraction. Users can quickly switch between applications and perform multiple tasks efficiently.
3. Easy to customize according to needs: Users can change the layout, color and size of interface components as desired. Create comfort when using and help users feel closer to technology.
4. Multi-device support: GUI is not only for computer use but also available on various devices such as smartphones, tablets and IoT devices. Bringing flexibility and convenience to users.

Some limitations

Despite its many benefits, GUI also has certain limitations that users need to consider as follows:

1. High resource requirements: The GUI requires a powerful processor and enough RAM to run smoothly. This can be difficult for people using old or low-spec computers.
2. Difficulty in interacting with the graphical interface: Although GUIs have been improved to be more user-friendly, many people still have difficulty interacting with the graphical interface.

How is GUI different from UI?

Although the two terms 'GUI' and 'UI' are often used interchangeably, there are distinct differences between them. Here are the most obvious differences:

Is GUI present on all operating systems?

Today's operating systems primarily use GUIs that allow users to interact with computers and devices through icons, windows, and menus. Some popular operating systems with GUIs include Windows, macOS, Linux, Android, and iOS.

1. Desktop: Most computer operating systems like Windows, macOS, and Linux come with a GUI, making it easy for users to operate using a mouse and keyboard.
2. Mobile devices: Mobile operating systems such as Android and iOS also use GUIs, although the interface may differ from desktop operating systems due to different screen sizes and intended uses.

Conclude

The graphical user interface is not only a tool but also a bridge between the user and the computer to make interaction easier. Through this article, you have clearly understood how GUI works as well as the history of its development. Although there are still some problems that need to be overcome, it can be said that the role of GUI is indispensable in modern life today.
