Graphical User Interface – GUI
A Graphical User Interface (GUI) is a user interface that allows users to interact with electronic devices in a highly graphical manner, with windows, icons, a mouse, and a pointer, instead of text-based interfaces, typed command labels, or text navigation. GUIs were introduced in response to the steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.
GUIs have significantly influenced software development processes. Early on, programmers needed to code all aspects of the interface, but with GUIs and the evolution of integrated development environments (IDEs), much of this process has become automated.
Drag-and-drop interfaces in these IDEs allow for the visual creation of windows, buttons, and other GUI elements, saving time and effort in development. GUIs have enabled non-programmers to develop software using visual programming languages.
