GUI stands for “Graphical User Interface” and facilitates the operation of end devices through visual elements such as icons and menus. This visual interface between man and machine improves user-friendliness and is used by both operating systems and applications.
Almost every end-user program today has a GUI. The main function of the GUI is to present the backend code in a user-friendly way, with icons and images playing a central role. As a fixed component of modern operating systems, it allows the use of input devices such as the mouse. A GUI is a visual representation of programs and functions. The use of GUIs improves user-friendliness by replacing text commands with visual elements. Developers use GUIs to combine visual design and programming with a focus on user-friendliness. Typical components of GUIs are input fields, windows, screens and buttons. GUIs use event-based programming to react to user actions.
A good GUI is characterized by simple interfaces, purpose-oriented layouts, consistency and a suitable design. It informs users about errors and status changes. Although GUIs offer advantages such as user-friendliness, there are also disadvantages such as increased resource consumption and more complex development compared to text-based user interfaces.
